Piazza is one of several words (including porch, portico, and veranda) used to describe covered walks or spaces supported by columns or piers and attached to, or to part of, a building. This architectural feature spoke to the interrelatedness of architecture and gardens, a relationship that grew out of the romantic interest in landscape characterizing the aesthetics of the eighteenth and nineteenth centuries. Two images exemplify the importance of these structures in creating and framing views of the garden and landscape. The first is a drawing of York Island, Long Island, by William Russell Birch (1808), who explained that the view was taken from the piazza, a place from which one could see "innumerable seats, spreading over an extensive country which glittered as the sun arose" [Fig. 1]. The second is from A. J. Downing's book on wooden picturesque houses, The Architecture of Country Houses (1850) [Fig. 2]. Both illustrate views from the bracketed piazza, or veranda, as Downing preferred to call it, out to the distant prospect.
Treatises often used these terms interchangeably, along with a few other less common words that were more or less synonymous. Downing and Alexander Jackson Davis used the term "umbrage" to refer to the same feature on a house, implying a place of shade; Downing used the term "pavilion" synonymously with "veranda"; and Mary Elizabeth Latrobe mentioned that in New Orleans the piazza was also known as the gallery (view text). Contrasting usage sometimes reveals distinctions. In his plan for a country house, Downing also used the term "porch" to identify the central area of the veranda leading to the entryway. The nineteenth-century architect William H. Ranlett sometimes distinguished between piazza and veranda, using "piazza" for a walk over which a projecting roof might be added, and "veranda" for a structure that included a roof (). Two points are important in the history of these terms: First, these architectural elements served to elide the boundaries of the garden and building by linking interior and exterior space both visually and physically. Second, the associative values of refinement and domesticity, and even national progress, were read into the forms.
In 1828, Frances Milton Trollope, the acerbic critic of American art and architecture, described the piazza as a "luxury almost universal in the country houses of America" (). Indeed it was a feature found throughout the colonies and dates from the late eighteenth to the mid-nineteenth centuries. From Massachusetts to the lower Mississippi Valley, examples are found on both private and public buildings. The feature was adapted to various styles with appropriate detailing and ornamentation. The piazza was a projecting porch or connecting passage that was identifiable in neoclassical plantation houses in the South, as well as in the Gothic revival suburban cottages of New Jersey and Pennsylvania. There were countless variations ranging from the simple wooden post-and-lintel type, to stone-arched piazzas depicted by Batty Langley [Fig. 3] and mentioned in 1839 at Laurel Hill Cemetery in Philadelphia (view text).
In texts and images related to American gardens of the period under study, although several imported treatises traced "piazza" back to covered walkways that surrounded the square, the term has not been associated with the Italian term for a medieval or renaissance square. It was generally described as two related but somewhat distinctive appendages to buildings. First, the piazza was attached porch-like to a façade so that three sides of the piazza projected out from the building [Fig. 4], or the sides were recessed into the structure, as on the main façade of the U.S. Naval Asylum in Philadelphia [Fig. 5]. At other times it appeared on more than one façade [Fig. 6]. In New Orleans one house was described as having piazzas on all four sides (view text). Both one- and two-story piazzas were also built. Second, "piazza" also referred to a covered walkway embedded between two buildings and acting as a connecting link. A single- or even double-height piazza, such as that described in 1799 on a property in Richmond, Va. (), provided either an entrance or transition space from interior architecture to exterior space. In the case of the University of Virginia, piazzas linked the entire range of houses around the lawn, and they served as transitional spaces leading to the lawn [See Fig. 12].
The piazza's basic structure consisted of a roof supported by pillars or columns. A piazza might be walled on each side with Venetian blinds or, as Harriet Martineau described one in 1835, "draperied with vines" (view text). Flooring was stone, flag, wooden planks, or gravel. The roof was generally either flat or peaked. James E. Teschemacher (1835), however, described and illustrated a piazza with a concave roof formed of painted floor cloth fastened on wooden rafters, which were supported by wooden arches (view text). Several images depict the piazza at ground level opening directly out into the landscape. Some examples, however, describe broad and spacious flights of stairs leading from the piazza and "descending into the garden" (view text). At Thomas Jefferson's Monticello (Charlottesville) and Poplar Forest (Bedford County, Va.), the piazzas had no immediate access to the ground but instead were raised, balcony-like structures overlooking the garden. Even if not a physical link, the visual connection to the exterior remained critical to the function of this feature.
The nineteenth-century architect William H. Ranlett, who used them often in his residential design, praised piazzas for their "very expressive" purpose (). They functioned as sitting areas that were furnished with couches, chairs, and sometimes tables where one could take a meal. They were used to provide a place for walking or sitting and enjoying the breeze, shade and coolness; they also served to keep the sun from warming the interior of the house. Since the feature was designed to provide views in addition to protection from the sun, orientation of the piazza had to be planned with regard to the sun and surrounding environment. At Hyde Park, a visitor in 1830 mentioned that one piazza was open to the Hudson River and the other looked over a beautiful lawn, suggesting that the view dictated where the piazzas might be located (view text).
Ranlett was emphatic when he decreed that a "dwelling should always have one or more of them [piazzas]." He regarded the absence of a piazza on a new house an indication of ignorance, niggardliness, and narrow-minded views (). Downing (1850) went so far as to proclaim the lack of a piazza or veranda in any but the most utilitarian structure as "unphilosophical and false in taste!" He claimed that it was a resting place, lounging spot, and place of social resort of the whole family across nearly the entire extent of the United States () [Fig. 7].

- "The house was quadrangular, with a high steep Dutch roof, immensely large and two stories in height. . . . [It was] built of wood, painted white, with Venetian blinds, and latticed verandas, supported by slender and graceful pillars, running round every side of the dwelling. . . . At each extremity of the piazza was a broad and spacious flight of steps, descending into the garden which enclosed the dwelling on every side. . . .
- "Around the semi-circular flight of steps, ascending to the piazza of the dwelling,—the columns of which were festooned with the golden jasmine and luxuriant multiflora,—stood, in large green vases, a variety of flowers . . . breathing gales of fragrance upon the air. From this point the main avenue branches to the right and left, into narrower, yet not less beautiful walks, which, lined with evergreen and flowering shrubs, completely encircled the cottage. . . .
- "Passing from this plantation scene through the airy hall of the dwelling, which opened from piazza to piazza through the house, to the front gallery, whose light columns were wreathed with the delicately leaved Cape-jasmine, rambling woodbine and honeysuckle, a lovelier and more agreeable scene met my eye. I stood almost embowered in the foliage of exotics and native plants, which stood upon the gallery in handsome vases of marble and China-ware. The main avenue opened a vista to the river through a paradise of althea, orange, lemon, and olive trees, and groves and lawns extended on both sides of this lovely spot, 'Where Flora's brightest broidery shone,' terminating at the villas of adjoining plantations."

- "A cottage on Jamaica Pond, for instance, within an easy ride of Boston, is a luxurious summer abode. I know of one unequalled in its attractions, with its flower-garden, its lawn, with banks shelving down to the mere; banks dark with rustling pines, from under whose shade the bright track of the moon may be seen, lying cool on the rippling waters. A boat is moored in the cove at hand. The cottage itself is built for coolness, and its broad piazza is draperied with vines, which keep out the sun from the shaded parlours."

The singular ranges of college buildings are visible from a considerable distance, as they advantageously crown an eminence, presenting the appearance of a piazza surrounding an oblong square, with the professors' houses rising at regular intervals. We found that the low buildings connecting these larger dwellings were the dormitories of the students; ground-floor apartments opening into the piazza, and designed to serve as places of study as well as sleep." [Fig. 12]
- "You are then invited to see the house, learning by the way the extent and value of the estate you are visiting, and of the 'force' upon it.

- "the absence of a piazza, the lack of all ornamentation, of vines and shrubbery [of a house recently erected in the suburbs of N.Y.], bespeak a degree of ignorance of the means of enjoyment, of niggardliness and contracted views, that ere long will be looked upon with incredulity."
- "Verandas, piazzas and porches are very expressive of purpose, and a dwelling should always have one or more of them; and balconies, which are decidedly ornamental and not without use."
- Downing, A. J., 1850, The Architecture of Country Houses ( 1968: 357-58), back up to history
- "The larger expression of domestic enjoyment is conveyed by the veranda, or piazza. In a cool climate, like that of England, the veranda is a feature of little importance; and the same thing is true in a considerable degree in the northern part of New England. But over almost the whole extent of the United States, a veranda is a positive luxury in all the warmer part of the year, since in midsummer it is the resting place, lounging spot, and place of social resort, of the whole family, at certain hours of the day. It is not, however, an absolute necessity, like a kitchen or a bed-room, and, therefore, the smallest cottages, or those dwellings in which economy and utility are the leading considerations, are constructed without verandas. But the moment the dwelling rises so far in dignity above the merely useful as to employ any considerable feature not entirely intended for use, then the veranda should find its place; or, if not an architectural veranda, then, at least, the arbor-veranda, covered with foliage. . . . To decorate a cottage highly, which has no veranda-like feature, is, in this climate, as unphilosophical and false in taste, as it would be to paint a log-hut, or gild the rafters of a barn: unphilosophical, because all that relative beauty suggested by features which indicate a more refined enjoyment than what grows out of the necessities of life should first have its manifestation, since it is the most significant and noble beauty of which the subject is capable; and false in taste, because it is bestowing embellishment on the inferior and minor details, and neglecting the more important and more characteristic features of a dwelling."
- "The art of landscape gardening is an essential part of the accomplishments of an architect, for the main beauty of a rural dwelling is its harmonizing with the scene of which it forms a part. The same house that looked picturesque and beautiful on the top of a hill would look extravagant and whimsical on a plain; a country house with a southern front should have a projecting roof and a piazza; but one fronting the north would look more cold and cheerless by the addition of an overhanging roof or a veranda. Yet nothing is more common than to see houses in the country with gloomy-looking piazzas on the north side which is always in shadow, while the back part is left to scorch in the sun without even the protection of a hooded window to cast a shadow."

- William Pierson, Jr., traces the origins of the feature, specifically found in Alexander Jackson Davis and A. J. Downing's work, to the awning or canopy partaking of an oriental flavor. In general, its origin was a semi-enclosed outdoor space that was not at all architectural but was related to the ornamental canopy or tent. This connection might explain why the detail flourished during the high romantic period in American architecture.
