Fort St. Catherine, or Fort St. Catherine's (as it is usually referred to), is a coastal artillery fort at the North-East tip of St. George's Island, in the Imperial fortress colony of Bermuda. Successively redeveloped, the fort was used first by Bermudian Militia and then by regular Royal Artillery units from 1612 into the 20th century. Today it houses a museum.
