The Nathaniel C. Allen House is a two-story Federal style residence located in New Gloucester, Maine. The house was built in 1793 by Shubael Marsh, a local builder (and father of ShubaelJr. (17971867), who moved to Texas with Stephen F. Austin) and sold to Nathaniel Coit Allen, an early settler in New Gloucester, who served as a General during the American Revolution. The property was purchased by Col. James Madison Thompson, then owner of the Glen House, an early White Mountains hotel in New Hampshire, who renovated the home by replacing the central chimney with two narrow ones and raised the ceilings and introduced Victorian interior woodwork. A subsequent owner added large Colonial Revival porches on the front and side entrances along with a new entry. The house showcases the changing tastes from Federal style to Victorian back to traditional tastes.
