The Saunderstown Historic District encompasses a section of Saunderstown which developed as a boatbuilding center and summer resort area in the late 19th century. It is centered on Ferry Road, Willett Road, and Waterway, between Boston Neck Road and Narragansett Bay. In addition to being home to a number of shipyards, several owned by members of the Saunders family, the area also became noted as a summer resort, hosting Benoni Lockwood and Frances Willing Wharton (a cousin to writer Edith Wharton), as well as the architect and artist Christopher Grant LaFarge, son of the artist John La Farge. This area is mainly residential, with wood-frame houses one or two stories in height, with vernacular styling. Non-residential buildings include a country store, recreation center (which was formerly a fire barn), and the Saunderstown Post Office, which was built in 1902 as a Baptist church.
