The feature known as belvedere, prospect tower, or observatory was a raised structure or tower placed either on top of a building or as an independent structure in the garden. The belvedere provided a viewing platform from which to look out to the garden or surrounding landscape. With a continuous tradition in Europe since the Renaissance, by the late 18th century the belvedere was recorded as being part of American gardens. Although many images have been collected illustrating this feature in American gardens, relatively few specific written references have been found. It seems that the terms “tower,” “pavilion,” “summerhouse,” “obelisk,” and “column” were all used interchangeably to describe multi-storied structures that permitted viewers to ascend to a height that would offer a new, broader view not available from ground level [Fig. 1]. Regarding André Parmentier’s Horticultural and Botanical Garden in Brooklyn, New York, A. J. Downing (1849) reported that although “the garden walks afforded no prospect,” from the summit of the tower, “a beautiful reach of neighborhood for miles was enjoyed.” In 1802 Eliza Southgate described the summerhouse at the Elias Hasket Derby Farm, which had a staircase “by which you ascend into a square room. . . it has a fine airy appearance and commands a view of the whole garden.”[1]

The belvedere in the garden was often the focus of highly inventive designs, such as the observation tower at Monticello. During the course of several years, Jefferson made alternate designs for a multi-staged tower [Figs. 2 and 3], in which he experimented with a Gibbsian round-headed cupola for one and for the other a castellated turret. This latter design represents an early American foray into the Gothic revival style that would become popular only after the turn of the century, as seen in a British example that J. C. Loudon had published in An Encyclopaedia of Gardening (1834) [Fig. 4]. Notes on the verso of Jefferson’s c. 1771 drawing indicate that the tower was intended for “directing the line of sight to Monticello.” He later changed his mind and planned a 200-foot tall column, with a balustrade at the top.[2]

Belvedere or prospect towers were designed in all shapes and sizes. The central characteristic of the feature was that it provided a viewing platform rising above the surrounding site, offering a beautiful view, a prospect, a bel vedere. The importance of the prospect is critical to understanding the belvedere in landscape design. Since ancient Rome, the awareness of the delights of the prospect guided the development of villa design.[3] The drawing of the belvedere in the grounds of the Vassall-Craigie-Longfellow House [Fig. 5] gives some sense of the concern for height; it is depicted as located on top of a hill with angles of sight measured from its peak to the lowest ground level. The image of the tower at Monte Video [Fig. 6] illustrates that the height of the belvedere contributed to its importance in the designed landscape.

The provision of height for a belvedere could be achieved either by building a multi-staged tower, as at Monticello and the Vassall-Craigie-Longfellow House, or by placing a viewing platform on top of another building or by using the natural eminence of a hilltop, cliff, or water’s edge. A painting of Harlem in Baltimore [Fig. 7] depicts both a prospect tower and a castellated belvedere surmounting the mansion itself. The Harlem tower, in fact, looks like a raised summerhouse. It was reported to be “a pavilion,” on an eminence under which was “a well-constructed ice vault.”[4]

The stylistic ornamentation and even basic shape of these constructions ranged broadly. A. J. Downing (1849) for example, as a proponent of rural architecture, recommended that prospect towers be constructed of rustic branches and thatch such as that at André Parmentier’s Horticultural and Botanical Garden in Brooklyn, New York. The observatory at Bute, Massachusetts, described by William Bailey Lang (1845), adhered more closely to the neoclassical tradition, and resembled a truncated obelisk, another popular form of belvedere. Observation towers in the form of monumental obelisks were frequently used for public monuments, beginning with Solomon Willard’s design of 1825 for the Bunker Hill Monument in Boston.[5]

The garden belvedere was carefully sited so as to take in the most desirable views of the property and the landscape surrounding it. For example, the location of the belvedere at Point Breeze in Bordentown, New Jersey, facilitated a view that encompassed both the natural and designed landscapes surrounding the mansion. A painting of Cannon House and Wharf depicts a prospect tower in the garden [Fig. 8]. This house belonged to the family of Capt. John Cannon, a prominent merchant in New York; the belvedere would have provided a fine view of the wharf and harbor that was the source of the family’s wealth and fame. A. J. Downing described an “American Mansion” with a plan that included a prospect tower “on a little eminence overlooking the whole estate,” suggesting again, the claim of ownership implied by the view.[6]

“Belvedere” or related words were often given as names to country seats in America. Estates called “Belvidere” could be found in the cities of Richmond and Baltimore and the state of New York, to mention just a few examples. It carried with it a sense of pride of ownership and the importance of selecting a site with a bel vedere (see Alcove, Eminence, Prospect, and View for further discussion of the significance and control of vision in American gardens).[7]

“In the evening. . . took a walk. . . to the Belvidere, about two miles out of New York towards the Sound, an elegant tea drinking house, encircled with a gallery, at one story high, where company can walk round the building and enjoy the fine prospect of New York harbour and shipping. You have a delightful sea view from thence, commanding Staten, Long Island and Governor’s Island, Paulus Hook, Brooklyn and the Sound.”

“FEW persons are aware of the advantages to be gained in prospect by a slight elevation upon their grounds. This Observatory, situated in the woods of BUTE, is only thirty feet high, yet from its top may be seen Boston, Cambridge, Charlestown, Chelsea, Dorchester, the Ocean, and the Hotel at Nahaut.” [Fig. 9]

“THE Ends and Extremities of a Park are beautified with Pavilions of Masonry, which the French call Belvederes or Pavilions of Aurora, which are as pleasant to rest ones self in, after a long Walk, as they are to the Eye, for the handsome Prospect they yield; they serve also to retire into for Shelter when it rains. The Word Belvedere is Italian, and signifies a beauteous Prospect, which is properly given to these Pavilions.”

“2619. The prospect-tower is a noble object to look at, and a gratifying and instructive position to look from. It should be placed on the highest grounds of a residence, in order to command as wide a prospect as possible, to serve as a fixed recognised point to strangers in making a tour of the grounds. It may very properly be accompanied by a cottage; or the lower part of it may be occupied by the family of a forester, gamekeeper, or any rural pensioner, to keep it in order, &c.”

Fig. 11, A. J. Downing, “Design for a rustic prospect tower,” in A Treatise on the Theory and Practice of Landscape Gardening (1849), 460, fig. 88.
“A prospect tower is a most desirable and pleasant structure in certain residences. Where the view is comparatively limited from the grounds, on account of their surface being level, or nearly so, it often happens that the spectator, by being raised some twenty-five or thirty feet above the surface, finds himself in a totally different position, whence a charming coup d’oeil or bird’s-eye view of the surrounding country is obtained. Those of our readers who may have visited the delightful garden and grounds of M. Parmentier, near Brooklyn, some half a dozen years since. . . will readily remember the rustic prospect-arbor or tower, Fig. 87, which was situated at the extremity of his place. . . from its summit, though the garden walks afforded no prospect, a beautiful reach of neighborhood for many miles was enjoyed. Figure 88 is a design for a rustic prospect tower of three stories in height, with a double thatched roof. It is formed of rustic pillars or columns, which are well fixed in the ground, and which are filled in with a fanciful lattice of rustic branches. A spiral staircase winds round the interior of the platform of the second and upper stories, where there are seats under the open thatched roof.” [Figs. 10 and 11]

“In the second story plan. . . we find four bedrooms of good size, with two small ones, one of them used as a dressing-room. There is also a bath-room, with space for a water-closet at the end of the entry. At a, a narrow flight of stairs ascends to the apartment, 9 by 9 feet, in the top of the tower—which may be a museum or a prospect gallery. . .
“A smaller and lighter flight of stairs ascends in the tower, from the chamber floor to the top, where there is an apartment, 10 feet square, which may be the private sanctum of the master of the house, or a general belvedere or ‘look-out’ for visitors, as the taste of the proprietor may lead him to appropriate it.” [Fig. 12]

“This latter apartment, a charming prospect gallery or belvedere in a country of varied scenery, would be a very agreeable feature.”

“In the large dressing room, 13 by 13 feet, there is a light and pretty staircase, rising to the apartment in the upper part of the tower. This latter apartment, a charming prospect gallery or belvedere in a country of varied scenery, would be a very agreeable feature ; hence, the bed-room, 16 by 20, connected with the dressing-room below, might be the "state bed-room," with both dressing-room and belvedere attached to it.” [Fig. 13]
