The Canterbury Green is roughly a rectangle of about 1.5 acres bounded by Route 169 (a designated scenic highway) on the west, the driveway of the church on the north and Library Road on the south. The eastern border is formed by the church parking lot situated to the northeast of the Congregational Church. The church is located about in the center of the green near its eastern boundary facing west. It is dramatically sited on a knoll overlooking the green that slopes downward toward Route 169. The church was constructed in 1960 on the site of the previous churches.

The parking lot is not visible from the highway because the ground slopes down toward the east. A new play area to the south of the church area is not as visible as it might be because it too is situated behind the knoll.

Sugar maple trees are planted in a row some distance from Route 169. Four other trees have been planted, one in each of the four corners of the green. The only marker is the Connecticut Historical Commission town sign near Route 169 not too far from the northwest corner. Other than trees, the sign and the play area for children, the green is bare.

The buildings clustered around the green provide enclosure for the open space. However, the rural nature of the community is evident when looking toward the southwest where open pasture punctuated with old stone fences is evident.
