Before the Hamptons were the Hamptons, there was this clutch of buildings, now nicely maintained and spread around Southampton. The main museum is Rogers Mansion, once owned by a whaling captain. You can also visit a former dry-goods store, now occupied by a local jeweler, around the corner at 80 Main St; and a 17th-century homestead, the Halsey House (adult/child $5/free, Saturday only, July to September).
Additional buildings include an 1830 one-room schoolhouse, an 1825 barn and a 19th-century paint store, among others.
