The Glastonbury Green, located within the Glastonbury National Register Historic District and within a local historic district, is rectangular in shape measuring approximately 250 feet by 900 feet. It is bordered by Smith Drive on the north; Hubbard Street on the south and east; and Main Street on the west. Each street is a two-way street. Parallel parking is allowed around the perimeter of the green on Smith Drive only. No parking is allowed on Hubbard Street.

The green is almost level, smoothly graded surface, draining to the east. It is planted with grass and is bounded by asphalt curb. Circulation is provided by a sidewalk along Hubbard Street but paths provide circulation across the green. The ground is well-maintained and liberally dotted with trees. Sugar Maple trees are planted along the perimeter at even intervals with plantings more dense on the north side of the green bordering both sides of Smith Street. Also present are beech trees, a large deciduous tree on the west end of the green, and a Colorado Spruce on the east side.

The focal point is a terraced area with a flagstone surface flanked by four granite war monuments in the center. The Vietnam, Korea, World War II and World War I monuments are flanking a granite Civil War Monument 1913) which consists of a Union soldier with a flag upon a tall base.

The Town Hall is located at the western end of the green along Smith Drive. It is sheltered by large trees. The old cemetery is sited along the north side of the green. The streetscape along the south side is comprised of residential buildings that date primarily from the 18th and 19th century and are oriented facing the green. The exception is a commercial warehouse building.

The green is used today for sport activities, band concerts, garden club sales, arts, crafts and antique shows and picnics.
