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.
