The green in Roxbury, located within a National Register Historic District, is a triangular greensward of about .5 acre at the intersection of Route 67, Church Street and Weller's Bridge Road. It is without trees and benches. Near the center is a granite obelisk honoring Seth Warner, a Revolutionary War hero buried beneath the monument. It is surrounded by shrubs and a flower bed. Near the monument is a flagpole kept lit at night by a spotlight mounted on it. There are several signs on the green, one identifying the road as a State Scenic Highway; one placing the green within a local historic district; and the other for the posting of town events.

The houses surrounding the green date from the 18th and 19th centuries. The exception is the library built in the first half of the 20th century. The Episcopal Church (1807-1817 on the northwest corner faces South Street away from the green and is not a strong presence. The green itself really amounts to little more than a traffic island. The more impressive aspect of the landscape are the buildings set back from the street to acknowledge the existence of the original green. They date primarily from the early 19th century and are ranged widely apart. At the eastern end of the original common is St. Patrick's Catholic Church (1885) and further to the east, the Congregational Church.

Otherwise, the properties are oriented facing the original town common along Church Street below the town green. They are well set back behind the fences and stone walls. Above the green, along Weller's Bridge Road, the terrain becomes steep and hilly. Mature trees provide shade along both sides of the original common. Roxbury has changed little architecturally since the early 19th century.
