The term terrace, used to describe both natural and artificial landscape features, denoted a level area or platform, often slightly raised and of varying dimensions and materials. Although Stephen Switzer (1718) made subtle distinctions between kinds of terraces (terrace walks, great terraces, middle terraces, etc.), those distinctions were not generally followed in American usage. In practice, however, a variety of terrace types were incorporated into landscape designs throughout 18th- and 19th-century America. These included long narrow terraces that formed raised walks, platforms of earthen and architectural materials adjacent to buildings, and earthen terraces between slopes in falling gardens.
Native American platform mounds, such as the one described as a terrace by William Bartram in 1791, served as stages for the religious and ruling elite of the southeast before European contact (view text). Visible for miles, these mounds are remarkable not only as architectural monuments but also as testimonies to the leadership that mobilized a massive labor force needed to move such a vast quantity of earth.
In Anglo-American gardens, long, narrow terraces provided raised walks that offered excellent viewing platforms, formed circulation routes through the landscape, and made ideal venues for social promenade, as depicted at the Battery Park in New York by the Illustrated London News in 1849 [Fig. 1]. In 1718, Switzer declared that gardens without these elevated walks “must be esteem'd very deficient.”(view text) Waterside terraces were particularly common in America, because they were created with the fill dredged from rivers and canals. Such terraces were built in residential settings, such as the gardens at Maycox Plantation in Virginia, which were described c. 1780–82 by François Jean Chastellux and at the Vassall-Craigie-Longfellow House in Cambridge [Fig. 2]. In public areas, terraces were found at the Battery Park, described in 1793 by John Drayton, and at the waterfront of Alexandria, Virginia, visited in 1830 by Frances Milton Trollope.
Terraces were also built adjacent to buildings, and were often created from the earth excavated from cellar construction. The term “terrace” referred to raised earthen platforms and to flat roofed structures, both of which were used as balconies, promenades, and viewing platforms. These terraces (paved, turfed, graveled, or covered in metal compounds, as advertised in the Federal Gazette in 1816) were occasionally also ornamented with statuary, vases, urns, and plantings such as flower beds or, more rarely, topiary. Charles Lyell recorded his observations of a highly ornamented terrace in Natchez, Mississippi, in 1846. A paved or turfed terrace extending from the house and often bounded by a balustrade was particularly popular in Italianate architecture of the 1830s and 1840s and was promoted by William H. Ranlett (1849) and Andrew Jackson Downing (1849). These terraces required substantial investment to construct and, when planted intensively, to maintain [Figs. 3 and 4]. As Jane Loudon observed in 1845, “[T]hey are chiefly adapted for mansions and places of considerable extent.” (view text) Downing suggested that the function of the English paved terrace was often accommodated in America by the veranda (view text).
Broad terraces located adjacent to a building provided a transition between the built architecture and the grounds, as Batty Langley, Bernard M'Mahon, John Abercrombie, and A. J. Downing all noted. The terrace also provided a vantage point from which to admire views and vistas. Both Abercrombie (1817) and J. C. Loudon's (1850) discussions of terraces emphasize the importance of selecting sight lines and of building proportionally in order to create an appropriate visual setting for a house, as well as to establish a viewing platform for looking outward. For example, the terrace at Point Breeze, which was described by Trollope and depicted in an anonymous engraving after Thomas Birch [Fig. 5], was placed to take advantage of striking vistas. Similarly, flat roofs of buildings (such as those at Monticello; the Waterworks at Fairmount Park in Philadelphia; and the White House in Washington, DC) served as elevated terrace walkways with views of distant scenery. A certificate for the Horticultural Association of the Hudson [Fig. 6] depicts an idealized garden (possibly based on Downing's Highland Place) that includes a terrace, seen at right, framing an extended view of the Newburgh Basin.
Terraces of varying widths were also employed in sites with a steep grade in order to make for arable and easily navigated level areas, to control erosion, and to create the visual effects made possible by a series of slopes and flats (see Fall). These terraces were supported by earthen slopes or masonry walls, supports which were referred to variously as banks, slopes, and terrace walls. They were also sometimes simply called by the more general term, “terrace,” as in William Dickinson Martin's 1808 description of a “perpendicular terrace” at Salem, North Carolina. Designs for public institutions, such as Charles Bulfinch's 1818 design for two wings to be added to the seat of Joseph Barrell in order to create the McLean Asylum [Fig. 7], used terraces to frame views of the buildings’ façdes while accommodating the slope of the land. The terraces of a falling garden were generally separated by turfed slopes or, less commonly, masonry walls. As Anotine-Joseph Dezallier d'Argenville (1712) noted, gardens were less susceptible to erosion if their terraces were created by cutting into an existing hillside rather than constructed out of fill (view text) [Fig. 8].The planting schemes of falling garden terraces varied from simple turf to kitchen and flower beds, although images of terraces rarely showed plantings in detail. Among the few surviving examples is Jefferson's diagram (c. 1804) for a garden olitory, in which he specified a hedge at the “foot of the terras” designed to accommodate differing heights of the lawn and kitchen garden. In 1840, C. M. Hovey referred to the efforts of the Messrs. Winship of Brighton, Massachusetts, to transform the embankment of a railroad right-of-way on Hovey's land into an attractive terraced garden (view text). While the use of terraces and slopes to create falling gardens seems to have declined in popularity after the early 19th century, its use continued through mid-century in large formal landscapes of public gardens, such as the University of Virginia, and anywhere uneven or steep topography offered a challenge.

A terrace of 70 or 80 feet long and about 40 wide is already made and in cultivation. A broad grass walk leads along the outer edge; the inner part is laid off in beds for vegetables. This terrace is to be extended in length and another to be made below it. The view it commands, is at present its greatest beauty."
- "A door opens at each end, one into the hall, and opposite, one into the terrace, from whence you have an elegant view of all the rivers &c. . . . Lengthways of the house, and thro' the hall, is a walk, which extends on a terrace at each end for some way. . . .

- "The aspect of Hyde Park from the river had disappointed me, after all I had heard of it. It looks little more than a white house upon a ridge. I was therefore doubly delighted when I found what this ridge really was. It is a natural terrace, overhanging one of the sweetest reaches of the river; and, though broad and straight at the top, not square and formal, like an artificial embankment, but undulating, sloping, and sweeping between the ridge and the river, and dropped with trees; the whole carpeted with turf, tempting grown people, who happen to have the spirits of children, to run up and down the slopes, and play hide-and-seek in the hollows."
- "The proprietor has a passion for gardening, and his ruling taste seems likely to be a blessing to the city. He employs four gardeners, and toils in his grounds with his own hands. His garden is on a terrace which overlooks the canal, and the most parklike eminences form the background of the view. Between the garden and the hills extend his vineyards, from the produce of which he has succeeded in making twelve kinds of wine, some of which are highly praised by good judges."

- Hovey, C. M., November 1840, "Notes on Gardening and Horticulture in Worcester, Mass.," describing the grounds of Messrs. Winship, Brighton, Mass. (Magazine of Horticulture 6: 402) back up to history
- "We recollect of reading, in the last volume of the Gardener's Magazine, some remarks on treating the ground on the margins of rail-roads, where there were embankments of any extent. These remarks we had marked for insertion in our pages, but had forgotten them until the present moment, when called to our mind as we passed the grounds of the Messrs. Winship, in Brighton. The road passes immediately through the nursery, dividing it in two parts; but these gentlemen have so arranged the sandy embankments with terraces, planted with shrubs, &c., as to render them very ornamental. We only wish that other gentlemen who are able, would take the same pride in improving the embankments where they pass through their lands."
- "The terraces of the Messrs. Winship are made in the following manner: the distance is from ten to fifteen feet. A wall is laid of about four feet; then a grass banking of some three to five more, at an angle of forty-five or fifty degrees; this is the first terrace, and the surface, (about five feet wide,) is filled with fine flowering shrubs and herbaceous plants; another grass banking of from five feet more, at the same angle, is thrown up, and the surface prepared and planted out with shrubs and plants. When in the vigor of growth and flowering, these terraces have a fine effect, contrasted with the barren sand, which happens wherever there is a cut of ordinary depth. We have annexed the following engraving, representing the same." [Fig. 11]

- "The main entrance to the west front is from Pennsylvania Avenue, where the grounds form a semi-circle, of which the avenue is the centre; a very broad walk leads from them, up the ascending surface, to the main steps, which descend from a broad semi-circular terrace: two other entrances of this part of the grounds are placed at the angles or sides of this semi-circle, which also, by a straight walk, lead up to the broad terrace. From this lower terrace, a long flight of steps leads to the upper one, upon which the building of the Capitol is placed: on the turf between the walks, are oval and circular beds, planted with shrubs and roses, and filled with dahlias and other annual flowers."

In the latter are seen terraces, with statues and cut evergreens, straight walks with borders of flowers, terminated by views into the wild forest, the charms of both being heightened by contrast. Some of the hedges are made of that beautiful North American plant, the Gardenia, miscalled in England the Cape jessamine, others of the Cherokee rose, with its bright and shining leaves."

- "A Terrass, is an artificial bank or mount of Earth, commonly supported with a fronting or facing of stone, and raised like a kind of Bulwark for the ornament of a Garden."
- Dézallier d'Argenville, 1712, The Theory and Practice of Gardening ( 1969: 75, 116-18) back up to history
- "TERRASSES, when rightly situated, are likewise of great Ornament in Gardens, for their Regularity and Opening; especially when they are well built, and beautified with handsome Stairs, and fine Ascents. Sometimes there are made under them, Vaults, Grots, Cascades, and Buffets of Water, with an Order of Architecture, and a great many Statues in Niches; and, on the Coping above, are set Vases and Flower-pots, orderly ranged and disposed. . . .
- "WHEN you meet with a Piece of Ground whose Shelving is very steep, as perhaps of the Hill A, which you would make practicable for a Garden, it may be order'd three several Ways.
- "First, By making Terrasses one above another, at several Heights, and supporting the Earth with sufficient Walls of Masonry.
- "Secondly, By making such Terrasses, as will support themselves without a Wall, by Means of Banks and Slopes cut at the Extremity of every Terrass.
- "THE Third Way is, to make no Terrasses in strait Lines, nor long Flats between; but only to contrive Landing-Places, or Rests, at several Heights, and easy Ascents and Flights of Steps for Communication, with Foot-Paces, Counter-Terrasses, Volutes, Rolls, Banks, and Slopes of Grass, placed and disposed with Symmetry, which are called Amphitheatres. ...
- "OF these three Manners, that with the Slopes is the least Expence, and that of the Ampitheatre the most magnificent; so that Terrass-Walls may be reckon'd to hold a Medium between the other two. . . .
- "THE Architect, or he that is to give the Design of a Garden, should carefully consider the Slope and Winding of the Hill, and raise and describe the Profil of it very correctly; that by making the best Advantage of the Situation, and distributing its Terrasses with Husbandry and Discretion, there may not be a great deal of Earth to remove, but that what is taken from Places that are too high, may serve to raise and make good those that are too low, which should be done with such Prudence and Circumspection, that you should neither be obliged to bring in Earth, nor have any to carry away, when your Terrasses are finished. . . .
- "TERRASSES should not be made too frequent, nor too near one another, that is, you should always make as few of them as possible; and by means of Levels, or Flats, continued as long as the Ground will permit, endeavour to avoid the Defect of heaping Terrass upon Terrass, it being very disagreeable in a Garden to be constantly going Up-hill, or Down-hill, without finding scarce any Resting-Place.
- "WHAT we call the Level, or Flat, is the Space of Ground contained between the Slopes of two Terrasses, that is to say, the Platform sustained by the Walls or Banks of the Terrasses, which, in Fortification, is call'd the Terra-plain."
- Switzer, Stephen, 1718, Ichnographia Rustica ( 1982: 150-52)
- "The Terrace seems to have been us'd a considerable Time since . . . But the nearest of our Derivations in English, is from the French, Terrace, or Terrasse; and they from the Italians, (from whom they, and almost all Europe, derive their Terms of Art relating to Building, Gardening, &c.) Terraza, Terrazare, signifying with them the removing and banking up of Earth, from one Place into another.
- "But be the Derivations as it will, it is very well known in these European Countries, and particularly with us, to be a small Bank of Earth, laid out and trimm'd according to Line and Level, being necessary for the proper Elevation of any Person that walks round his Garden, to view all that lyes round him. And this Elevation is so necessary, that all Gardens must be esteem'd very deficient, that have them not . . . that I dare pronounce a Seat of no Value without them; and, besides, where-ever the House is to be new built, there is no Possibility of disposing of the Earth, Clay, Rubbish, &c. that necessarily comes out of Cellars and Foundation thereof, but this; which we must otherwise suppose (amidst a thousand needless Works) is to be carted away, to fill up some Hollow or other, which had been better left undone perhaps likewise.
- "Of Terrace-Walks there are several Kinds, as they are particularly us'd.
- "The 1st, is that great Terrace that lies next the House.
- "The 2d, Side, or Middle Terrace, that is commonly rais'd or cut out above the Level of the Parterre, Lawn, &c.
- "The 3d, Those that encompass a Garden; and
- "The 4th, Many that lye under one another, as being cut out of a large high Hill; these are differing, in some Respect or other, from one another."
- "When the Situation of Gardens such, that the making of Slopes and Terraces are necessary, or cannot be avoided, they not only leave them naked of Shade as aforesaid, but break their Slopes into so many Angles, that their native Beauty is thereby destroy'd. Thus if by waste Earth a Mount be raised ten or twelve Feet high, you shall have its Slope, that should be entire from top to bottom, broken into three, if not four small trifling ones, and those mixt with Archs of Circles, &c. that still adds to their ill Effects: So that instead of having one grand Slope only with an easy Ascent, you have three or four small ones, that are poor and trifling.
- "And the only reason why they are made in this Stair or Step-like manner, is first to shew their Dexterity of Hand, without considering the ill Effect; and lastly to imitate those grand Amphitheatrical Buildings, used by the Ancients, of which they had no more Judgement, than of the excellent Proportions of Architecture that was used therein, when those noble Structures were first erected. . . .
- "When very large Hills of great perpendicular Heights are to be cut into Slopes and Terraces, then we may justly endeavour to imitate those grand Structures, (whereon their Gladiators exercis'd) by cutting them Concave, Convex, &c. as those looking towards Fair-Mile Heath, in the Gardens of his Grace the DUKE of NEWCASTLE at his Grand Seat of Claremont; but in small Elevations they are poor and trifling, and therefore not to be used."
- "TERRACES:A Terrace is a small Bank of Earth, rais'd and trimm'd according to Line and Level, for the proper Elevation of any Person that walks round a Garden, that he may have a better Prospect of all that lies around him; and these Elevations are so necessary, that those Gardens that have them not, are deficient.
- "When Terraces are rightly situated, they are great Ornaments to such Gardens as have them, for their Regularity and Opening; especially when they are well built, and beautify'd with handsome Stairs, and fine Ascents.
- "There are several Kinds of Terrace-walks:
- "1. The great Terrace, which lies next to the House.
- "3. Those Terraces which encompass a Garden.
- "4. Those Terraces which lie under one another, being cut out of a large Hill; and these are different one from another, in some respect or other.
- "As to the Breadth of side Terraces, this is usually decided by its Correspondence with some Pavilion, or some little Jettee or Building; but most of all by the Quantity of Stuff that is to spare for those Purposes.
- "The side Terrace of a Garden ought not to be less than twenty Feet, and but very seldom wider than forty.
- "As for the Height of a Terrace, some allow it to be but five Feet high; but others more or less, according to their Fancies; but the more exact Persons never allow above five or six Feet; and in a small Garden, and a narrow Terrace walk, three Feet; and sometimes three Feet and an half high are sufficient for a Terrace eighteen Feet wide; and four Feet are sufficient for a Terrace of twenty Feet wide; but when the Garden is proportionably large, and the Terrace is thirty or forty Feet wide, then it must be at least five or six Feet high.
- "The noblest Terrace is very deficient without Shade; for which Elm-trees are very proper: for no Seat can be said to be complete, where there is not an immediate Shade almost as soon as out of the House; and therefore these shady Trees should be detach'd from the Body and Wings of the Edifice.
- "Terraces should be planted rather with Elm or Lime-trees, than with Yew or Holly; which will not grow large enough to afford Shade.
- "The Distance of the Elms across will be about twenty Feet; and they may be plac'd thirty Feet asunder in Lines."
- Salmon, William, 1762, Palladio Londinensis (n.p.) 
- "Tarrau, or Tarras, an open Walk, or Gallery; also a flat Roof on a House; also a Kind of coarse Plaister, durable in the Weather."
- Marshall, Charles, 1799, An Introduction to the Knowledge and Practice of Gardening (1:124) 
- "A terrace as a boundary is now seldom formed, but in some situations, such as an eminence might in several respects, be agreeable."
- "In other parts are sometimes discovered eminences, or rising grounds, as a high terrace, mount, steep declivity, or other eminence, ornamented with curious trees and shrubs, with walks leading under the shade of trees, by easy ascents to the summit, where is presented to the view, an extensive prospect of the adjacent fields, buildings, hamlets, and country around, and likewise affording a fresh and cooling air in summer. . . .
- "Fountains and statues, are generally introduced in the middle of spacious opens . . . sometimes in woods, thickets, and recesses, upon mounts, terraces, and other stations, according to what they are intended to represent. . . .
- "Regular terraces either on natural eminences or forced ground were often introduced by way of ornament, for the sake of prospect, and of enjoying the fresh air in summer; they were of various dimensions with respect to height, from two, to ten, or twenty feet, according to the nature of the situation and purpose they were designed for; some being ranged singly, others double, treble, or several, one above another, on the side of some consideable rising ground in theatrical arrangement."
- "If flights of stone-stairs and ballustrades are not the inseparable accompaniments, if the term terrace is merely to designate a raised walk, many situations may be imagined, in which a terrace would both conduce to the accommodation of the proprietor of the grounds, and, without dispute, improve the view.
- "The view FROM the house, and TO the house, cannot always be consulted with mutual improvement. When a high terrace with ornaments which appear to mark the boundary of the architect's province, is interposed between the house and the lawn, the view immediately under the windows cannot certainly be so pleasant as if the house stood in a verdant field:—but let the prospect be reversed, and every stranger will see more grandeur in the house connected by a terrace with the garden; and perhaps among the spectators under the influence of cultivated taste, a few may think such a gradation conduces to general harmony.
- "In a flat, or confined situation, a terrace with sloping grass banks may create a prospect, or relieve the sameness of the scenery."
- "1933. Levelling for terrace-slopes ... or for geometrical surfaces, however varied, is performed by the union of both modes, and requires no explanation to those who have acquired the rudiments of geometry, or understand what has been described. . . . [Fig. 13]
- "7256. Terrace and conservatory. We observed, when treating of ground, and under the ancient style, that the design of the terrace must be jointly influenced by the magnitude and style of the house, the views from its windows, (that is, from the eye of a person seated in the middle of the principal rooms,) and the views of the house from a distance. In almost every case, more or less of architectural form will enter into these compositions. The level or levels will be supported partly by grassy slopes, but chiefly by stone walls, harmonising with the lines and forms of the house. These, in the Gothic style, may be furnished by battlements, gateways, oriels, pinnacles, &c.; or, on a very great scale, watch-towers may form very picturesque, characteristic, and useful additions. . . .
- "7257. The breadth of terraces, and their height relatively to the level of the floor of the living-rooms, must depend jointly on the height of the floor of the living-rooms and the surface of the grounds or country to be seen over them. Too broad or too high a terrace will both have the effect of foreshortening a lawn with a declining surface, or concealing a near valley. The safest mode in doubtful cases is, not to form this appendage till after the principal floor is laid, and then to determine the details of the terrace by trial and correction.
- "7258. Narrow terraces are entirely occupied as promenades, and may be either gravelled or paved: and different levels, when they exist, connected by inclined planes or flights of steps. Where the breadth is more than is requisite for walks, the borders may be kept in turf with groups or marginal strips of flowers and low shrubs. In some cases, the terrace-walls may be so extended as to enclose ground sufficient for a level plot to be used as a bowling-green or a flower garden. These are generally connected with one of the living-rooms or the conservatory, and to the latter is frequently joined an aviary and the entire range of botanic stoves. Or, the aviary may be made an elegant detached building, so placed as to group with the house and other surrounding objects."
- "Terrace-gardens are merely architectural-gardens, formed on platforms adjoining the house, on one or more levels, each level being supported by a terrace-wall; but as they are chiefly adapted for mansions and places of considerable extent, where of course a regular gardener must be kept, it does not appear necessary to enlarge on them here."
- "The garden of the Elizabethan villa should be laid out with a few simple terraces near the house, so as to unite it well with the ground."
- "TER'RACE, n. [Fr. terrasse; It. terrazzo; Sp. terrado; from L. terra, the earth.],
- "1. A raised level space or platform of earth, supported on one or more sides by a wall or bank of turf, &c., used either for cultivation or for a promenade.
- "2. A balcony or open gallery. Johnson.
- "3. The flat roof of a house."

- "Where it is desirable to separate the house from the level grass of the lawn, let it be done by an architectural terrace of stone. . . .
- "In a succeeding section we shall refer to terraces with their parapets, which are by far the most elegant barriers for a highly decorated flower garden, or for the purpose of maintaining a proper connexion between the house and the grounds. . . .
- "the long veranda round many of our country residences stands instead of the paved terraces of the English mansions as the place for promenade. . . .
- "In our finest places, or those country seats where much of the polish of pleasure ground or park scenery is kept up, one of the most striking defects is the want of 'union between the house and the grounds.' ...
- "Let us suppose . . . The house now rising directly out of the green turf which encompasses it, we will surround by a raised platform or terrace, wide enough for a dry, firm walk, at all seasons; on the top of the wall or border of this terrace, we will form a handsome parapet, or balustrade, some two or three feet high, the details of which shall be in good keeping with the house. . . . On the coping of this parapet . . .we will find suitable places, at proper intervals, for some handsome urns, vases, etc. On the drawing-room side of the house . . . we will place the flower-garden, into which we descend from the terrace by a few steps. . ..
- "The eye now, instead of witnessing the sudden termination of the architecture at the base of the house, where the lawn commences as suddenly, will be at once struck with the increased variety and richness imparted to the whole scene, by the addition of the architectural and garden decorations. . ..
- "Where there is a terrace ornamented with urns or vases, and the proprietor wishes to give a corresponding air of elegance to his grounds, vases, sundials, etc., may be placed in various appropriate situations. . . .
- "The only situation where this brilliant [white] gravel seems to us perfectly in keeping, is in the highly artificial garden of the ancient or geometric style, or in the symmetrical terrace flower garden adjoining the house. In these instances its striking appearance is in excellent keeping with the expression of all the surrounding objects, and it renders more forcible and striking the highly artificial and artistical character of the scene; and to such situations we would gladly see its use limited."
