Valour Green is a large triangle at the intersection of Main Street (a four-lane highway) and Prospect Hill Road. The northern boundary is sharply marked by dense plantings and some large hemlocks. It is bisected by Fritsch Drive (so named to honor Cromwell's single Vietnam War fatality), creating a long and narrow triangle at the southern end. The entrances to Fritsch Drive from Main Street and Prospect Hill are flanked by brick pillars bearing the name of the road.

There are two large Norway spruce trees and a Constitutional pin oak which was planted in 1902, blown over by the 1928 hurricane, and subsequently replanted. On the lower triangle are 20 flowering trees (eight dogwood; four hydrangea; and eight crabapple) planted in a random pattern. A single asphalt path cuts diagonally across the green just north of Fritsch Drive. It is well-maintained.

Along Prospect Hill Road, residences from the early-19th century to the mid-20th century face the green. The western side of the green is dominated by greenhouses and other buildings associated with A.N. Pierson, Inc., a floral nursery established in the last half of the 19th century along the fertile alluvial flood plain west of Main Street. Also associated with the Pierson family is "Holy City," a group of buildings erected between 1922 and 1925 north of the green but not visible from it because of the dense trees along the border. The family's adherence to the Russellite faith, a dogma which espouses the eminent end of the world, was the impetus for their construction. An octagonal building originally built as a private school is included as part of the complex.

The large green houses and industrial structures along Main Street are somewhat visually disconcerting in their proximity to the green. But they are historically important in that many of the buildings along Main Street are associated with these and other industries that developed in the area in the 19th century. Valour Green, however, covers a large area and is less susceptible to what is happening along its borders than are smaller open spaces.
