The Naval Yard was initially defended by its own large blockhouse , three redoubts and a fortified stone wall . These defences were enhanced and later replaced by the large network of army fortifications whose main purposes was to safeguard the Naval Dockyard including nearby Fort Needham , Fort George , the Halifax Citadel ; York Redoubt ; Fort Charlotte on Georges Island , Fort Clarence in Dartmouth ; five forts on McNabs Island and extensive batteries at Point Pleasant . Many of the original Royal Navy 18th and 19th century buildings in the Dockyard were destroyed in the 1917 Halifax Explosion ; others were demolished in World War II to make way for machine shops , stores buildings and drill halls needed to man and maintain the many escort ships being commissioned during the crash expansion of the Royal Canadian Navy during the Battle of the Atlantic . Only one residence from 1814 and the Admiral 's Residence from 1816 survived . The Admiral 's residence in now the Maritime Command Museum . The original Naval Yard clock has been restored and moved to the Halifax Ferry Terminal entrance while the original Naval Yard bell is preserved at the Maritime Museum of the Atlantic in Halifax , a museum which also features a large diorama depicting the Naval Yard in 1813 at its height in the Age of Sail
