Along the 800 foot length of the largest parcel is located the Town Hall, the Congregational Church, a former chapel (now a gallery), the parsonage and the former house of Eleazor Wheelock (c. 1736), the Congregational minister from 1735 to 1769. A new Victorian Revival gazebo is located in the center. Near the intersection is the town historical marker and a World War I memorial (1919) consisting of a bronze marker on a fieldstone boulder. The Daughters of the American Revolution placed a monument to Eleazor Wheelock in front of the church in 1949.

The green, as a wide open space at the center of the town, is marred by the traffic signals strung across the street, sign posts, huge electric light standards with wires criss-crossing overhead and smaller abandoned sections of grass traversed by unkept driveways. As is the fate of a green located at a major intersection, the traffic routes govern much of the scene and activity around it.

However, around the green and intersection are located the important civic and religious institutions; residences dating from the 18th, 19th and 20th centuries; two commercial buildings and the town's first burying ground. All of these properties are described in the Columbia Green National Register Historic District nomination. Several have local historic significance because of associations with important personages and because of their exceptional architectural qualities. Of particular note is the Eleazor Wheelock House (c. 1735); the Indian Charity School 1755); the Congregational Church; and the inn on the southwest corner known as the Landmark Inn (c. 1750) where General Rochambeau's officers were accommodated as they scouted the route to Yorktown.

Because it is located close to the intersection, the modern St. Columbia Catholic Church (1953), a brick building with a tall spire, visually dominates the historic crossroads community.
