The National Museum of Bermuda, previously the Bermuda Maritime Museum from its opening in 1974 until 2009 (legislatively formalised in 2013), explores the maritime and island history of Bermuda. The maritime museum is located within the grounds of the fortress Keep of the former Royal Naval Dockyard in Sandys Parish on the Ireland Island at the western end of Bermuda. The museum publishes a number of books relating to Bermuda's history.
