Aquatic Park Bathhouse Building/Maritime Museum is at 900 Beach St. Built in 1939, its Art Deco-inspired exterior mimics an ocean liner. Displayed in the lobby are fanciful and colorful murals, several miniature model ships encased in glass, a large chunk of the vessel Niantic. You'll also see the 19-foot sloop Mermaid, which 23-year-old Kenichi Horie used to sail solo across the Pacific in 1962. The veranda is open to the public. Changing exhibits are presented as well.
