The Federal Hill Green, located within the Federal Hill Historic District, is on the summit of a steep hill above the present commercial center of the City of Bristol. The green serves as small (approximately one acre) triangular park bordered by churches; residences (at least one converted to multi-family housing; a cemetery and a Catholic school. The green is mostly flat, rising slightly to the north, except for the southeast corner which forms a rocky rise behind the playground area then drops off steeply to the corner of Queen and Center Streets. This southeast corner is heavily wooded; the balance of the green is primarily open greensward. A playground area near Center Street is shaded by two large trees (one of which may be a scion of the charter oak described by the town historian - a small monument near the tree is missing its identifying plaque) and a landscaped area surrounding the flagpole at the north end of the green includes two dogwoods and two oak trees. Additional trees are planted along the boundaries of the green and along the walkway from Center to Queen Streets.

The playground area is identified by a wood sign as the "James F. Riordan Playground," includes brightly-painted metal play equipment. It is separated from the larger ball diamond area of the green by a concrete walkway and a rail fence.

The ball diamond area that has a small backdrop at the north end; bare spots in the grass in front of the backdrop, at pitcher's mound and along base lines indicates that the diamond is used. This ball diamond area is separated from the north end of the green and from Maple Street by more rail fences.

The north end of the park has a flagpole and a small monument identifying the colonial and present-day uses of the Federal Hill Green. This end of the green is landscaped with shrubs, trees, annual flower beds, benches and trash receptacles. A concrete walkway crosses the green between Maple and Queen Streets at the north end. There is also a concrete walk on the green along Maple Street and another crossing the green diagonally from the intersection of Maple and Center Streets to Queen Street near the Catholic church. This latter walkway is lit by lantern-like lights mounted on wooden posts. Electrical wires are underground.

Wood signs at the north end of the green and at the Maple/Center Streets corner identify the "Federal Hill Green." There are benches and trash receptacles (identical to those at the north end of the green) near the playground area at the south end of the green.

The 19th-century neighborhood along Center Street defines the southern boundary of the green and provides enclosure at that end. The larger institutional buildings along Maple and Queen Streets dominate the green but are interrupted by large parking lots and the cemetery and provide little sense of enclosure.
