Named after Admiral Nelson, the shipyard in the English Harbor many years ago caused the island of Antigua to be mapped on the world map. The museum recreates the history of the harbor, which was first used in the 17th century as a refuge for warships of the British Royal Navy. The shipyard built here was designed to provide the fleet with a reliable base with which it was possible to maintain a dominant position in this region over other European military forces. The island was never conquered by any other army, to a greater extent due to the strategic decision to place the dock in a convenient harbor, protected from several sides by mountains. It was this circumstance and the subsequently built Shirley Heights fortress that made the island impregnable.
