The area generally considered to be the Fairfield Town Green is the rectangular-shaped front lawn of the Town Hall along the Old Post Road. It is part of what today is the Historic Civic Center owned and maintained by the town, a twenty-acre site occupying the northeast corner of what once was Burr Square. The area immediately to the north across the Old Post Road, the site of the First Congregational Church and the Historical Society, in the early years contained the principal town buildings. On the southern boundary of the Civic Center, separated by several home sites, is the earliest town burying ground.

The Old Post Road is a busy, two-lane street that borders the green to the north. It is one long block south of Route 1 and Fairfield's commercial strip, and as a result is fairly busy. Town Hall Road, a one-way drive that provides vehicular access to the Town Hall from the Old Post Road is the western and southern boundary. To the East is Beach Street, another two-lane street. Although the green is the focal point of the town's civic activities, it is situated in what is primarily a residential neighborhood.

Diagonal slate paths starting at the northeast and northwest corners of the green meet in front of the Town Hall, the green's focal point. An asphalt path runs along the Old Post Road and just inside the green along Beach Street. Around it is an asphalt curb.

The green is shaded with mature trees, (primarily maple and some oak) randomly planted throughout. Near the corner of Beach Road and the Old Post Road is a large conifer used as a Christmas tree. Three small circular flower beds and a rectangular one located near Town Hall add color to the green.

In the center of the green near the Old Post Road is a large War memorial in the shape of a Greek temple with smaller temples on either side listing the names of those who served in World Wars I and II, the Korean War and Vietnam War. It is landscaped with flowers and ground cover and lighted.

Because of its considerable width and its location close to the sidewalk, it tends to hide the interior of the green from the street. Beside and to the west of it is a large boulder with a bronze plaque dedicated to Vietnam veterans. On the other side is another boulder with a bronze plaque commemorating the settlement of Fairfield by Roger Ludlow in 1639 and the burning of Fairfield by the British in 1770 (1900). Just to the west and east of this boulder is the town signpost, painted white. Near the center of the green is a large flagpole.
