The Tolland Green, situated on an elevated plateau, is a long (.5 mile) and extremely narrow (40 feet) strip of land oriented on a north-south axis. Cohesively ranged around it are 18th and 19th century houses and civic and religious buildings that functionally, visually, and historically relate to the green. (They are further described in the Local Historic District Committee Study Report.) Route 195 divides at the green and thus provides both the east and west boundaries. To the south is the Old Boston Post Road. The Tolland Stage Road (Route 74) goes through from east to west cutting it into two parcels. To the north is a remnant of the common land that was originally set aside. It appears to be a part of the lawn of the buildings that border it, but it is owned by the town and maintained by the abutting property owners.

Predictably, the civic buildings are located near the intersections. On either side of the green at the south end, at the intersection of the Boston Post Road, are two town halls, the Old Town Hall (1879) and the present Town Hall (1909). The Congregational Church, the Old Tolland County Court House (1822; now a library), the Board of Education building (in a converted residence built in 1830), and the Old Tolland Jail (now a museum) are located near the intersection where the Tolland Stage Road cuts through the green. The remaining buildings are residential; an impressive number date from the 18th and 19th centuries.

The green itself is smoothly graded and gently slopes from west to east and north to south. A line of about fifteen shade trees, mostly sugar maple, are planed down the center. At the south end is a flag pole war memorial and a conifer.
