Shot yard battery, which is located at the far south western end of the Castle complex, was constructed in 1874 as part of of a major re-armament of Dover Castle. It is one of four new batteries constructed within the castle at this time, the others being East Demi Bastion, Shoulder of Mutton Battery and Hospital Battery. Two 10-inch RMLs (Rifled Muzzle- Loading guns - loaded through the muzzle and with a rifled bore) were located here, together with a central shell and cartridge store.
