Terry-Ketcham Inn is a historic inn and tavern located at Center Moriches in Suffolk County, New York. It was built about 1693, expanded about 1710 and 1790, and is a two-story, nine-bay by two-bay frame structure with a rear wing and gable roof. The original structure was built as a two-bay by three-bay, single-story timber-frame cottage. In about 1710 a three-bay by two-bay timber frame half-house was built to the north of the original structure. A 1790 building program tripled the size of the structure.[2]
