Although landscaping the State House Yard had been long discussed, nothing of consequence appears to have been done in this regard during the Colonial period. At the time of the American Revolution, the square apparently was more or less barren, with no planned landscaping or system of walks. Cannon, which must have been a prominent feature of the yard, were parked within the walls. [Illustration: _Independence Square from Walnut Street gate, looking north._ Ink sketch from an early photograph.] With the return of peace, interest was again awakened in improving the grounds. Landscaping was finally begun about 1784 under the direction of Samuel Vaughan, a wealthy Jamaica sugar planter then living in Philadelphia. In addition to the wide central walk of gravel, leading from the tower door to the Walnut Street gate, and the serpentine walks about the perimeter of the square, the most noticeable feature of the yard was the assortment of 100 elm trees presented to the Commonwealth by George Morgan, of Princeton. Shortly after the landscaping was completed, the Reverend Manasseh Cutler visited this square and described it in his journal as a “fine display of rural fancy and elegance.” The trees are yet small, but most judiciously arranged. The artificial mounds of earth, and depressions, and small groves in the squares have a most delightful effect. The numerous walks are well graveled and rolled hard; they are all in a serpentine direction, which heightens the beauty, and affords constant variety. That painful sameness, commonly to be met with in garden-alleys, and other works of this kind, is happily avoided here, for there are no two parts of the Mall that are alike. Hogarth’s “Line of Beauty” is here completely verified. [Illustration: _Triumphal arch for Lafayette’s visit to Independence Hall, September 28, 1824._ Unidentified engraving (c. 1824).

In that year, when the old wing buildings were demolished to be replaced by “modern” office buildings, the high brick walls were removed to allow a “freer circulation of air.” In their place was erected in the following year, a low brick wall, about 3 feet high, with a marble coping surmounted by a railing of plain iron palisades. Access to the square was provided by a large gate on Walnut Street and smaller ones on Fifth and Sixth Streets, about halfway between Chestnut and Walnut.
