Little Plain Park, located within a National Register and local historic district, is a long and narrow triangle bounded by a sidewalk, mature trees and a handsome fence. The .69 acre greensward is situated within a fine residential neighborhood developed between the mid-18th century and the last quarter of the 19th century. It is situated at the intersection of Broadway and Union Street and bordered by Crossway Street on the south. A paved path cuts across it at about midpoint. The focal point is the Civil War monument, a stone obelisk, at the northern tip, dedicated to the 28th Regiment of the Connecticut Volunteer Infantry. Toward the southern end is a pink stone fountain honoring the two founders of the park, (1909) Hezekiah Perkins and Deacon Jabez Huntington. The most interesting feature is the fence, probably erected during the second half of the 19th century, and comprised of metal stiles between stone rails, which makes the open space more formal than the other Norwich greens. Unfortunately, it has suffered from vandalism and/or poor maintenance in that sections of it are missing.

The neighborhood around the green is comprised of impressive domestic structures that are further described in the National Register nomination. The only institutional building is the Catholic Church (c. 1876) north of the green. The buildings are well maintained and their integrity intact.
