Prudence Crandall Museum

The Canterbury Female Boarding School, in Canterbury, Connecticut, was operated by its founder, Prudence Crandall, from 1831 to 1834. When townspeople would not allow African-American girls to enroll, Crandall decided to turn it into a school for African-American girls only, the first such in the United States. The Connecticut legislature passed a law against it, and Crandall was arrested and spent a night in jail, bringing national publicity. Community violence forced Crandall to close the school. The episode is a major incident in the history of school desegregation in the United States. The case Crandall v. State was "the first full-throated civil rights case in U.S. history.... The Crandall case [in which a key issue was whether blacks were citizens: 144 ] helped influence the outcome of two of the most fateful Supreme Court decisions, Dred Scott v. Sandford in 1857[] and...Brown v. Board of Education in 1954.": xi

March Route of Rochambeau's Army: Manship Road-Barstow Road is a historic site in Canterbury, Connecticut that was listed on the National Register of Historic Places in 2003, for its evocation of the march route French commander Rochambeau's troops in 1781 and in 1782. It is significant as a preserved section of the march route which, in this area, is followed by what is now Connecticut Route 14. This section, however, is a bypassed loop of road, cut off by a road realignment in the 1930s, and therefore without traffic and not modernized. The section is approximately 1,400 feet of bypassed loop of road, on the north side of the main road, along Manship Road and Barstow Road, starting from a junction of the loop with Manship Road and running to Westminster Road. It is paved road about 20 feet wide, plus a margin to stone walls lining the road. The designated area is about 50 to 55 feet wide, extending to the walls. The National Register nomination of 2001 includes six photos of narrow roadway, stone walls, and the one house along this section. The house is itself historical, dating from about the 1840s, and adds rather than detracts from the historical feel.Rochambeau's troops marched through here in June, 1781, and found the road along this general area to be the most difficult along their whole journey. Although the road has been paved, the visual appearance is still evocative of passage of troops.Other preserved sections of the route nearby include March Route of Rochambeau's Army: Old Canterbury Road (about 2 miles (3.2 km) to the east, along Route 14 through Canterbury then straight on 14A, Canterbury Road) and March Route of Rochambeau's Army: Palmer Road (an approximately 2,000-foot (610 m) stretch about 3 miles (4.8 km) to the west along Route 14). Multiple other properties whose association with Rochambeau's route is known were also considered for listing on the National Register in a 2001 study.

Other architecturally prominent buildings include the c. 1855 Italianate mansion of mill owner Arthur Fenner, and the 1845 Greek Revival Congregational Church.The area that is now Central Village was a typical agricultural area until 1814, when a consortium of locals built a small cotton mill on the banks of the Moosup River. This enterprise gradually expanded, with the owners building housing for the mill workers, creating a small village. In 1845 the Central Manufacturing Company, then the village's largest employer, built a brick mill. The village's growth was encouraged by the arrival of the railroad in 1839, which was run midway between two mill locations. The cotton mills declined in the late 19th century, but its economy was propped up by other industries until the early 20th century, when the Plainfield Woolen Company revived the textile industry, building the principal surviving mill building.
