Marietta contains an architectural gallery of historic homes including Victorian, Colonial American, Gothic Cottages, and Log cabins. Marietta also boasts a National Historic District that encompasses 45% of the town. Four of these historic buildings have been restored for public use; the old Town Hall: that houses a museum, the old Bank: that house a gift shop, the Union Meeting House, and the Community House.
