Hammond Castle Museum was built in the late 1920s in the style of a medieval castle as the home and laboratory of John Hays Hammond, Jr, one of the most prolific inventors of the 20th century. The museum’s collection includes ancient artifacts and architectural elements such as the facades of 15th century French storefronts. Guests may explore many of the museum’s rooms and enjoy the beauty of the grounds and view of the Atlantic coast. The museum offers numerous educational and cultural programs throughout the season and is available for private rentals. At nearly a century, it is not handicapped accessible. It is listed on the National Register of Historic Places.
