H.M. Dockyard Gibraltar from 1903 to the end of 1984. To form the yard, reclamation works were undertaken and the harbour was dredged to take the largest warships afloat in 1890. Stone was quarried and brought to the south of Sandy Bay and transported via tunnels to the yard that emerges at Ragged Staff.
The principal building in the yard, the Tower, is now the office of the Commander of the British Forces, Gibraltar. It is a grand stone building with balconies and an elaborate tower. The main workshops and stores are stone-faced with the walls articulated by rows of large Tuscan pillars. The Yard was laid out from 1893 to 1907.
