Rock Gun Battery
Rock Gun Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on the North Face of the Rock of Gibraltar at the northern end of the Upper Rock Nature Reserve, above Green's Lodge Battery. The emplacement on Middle Hill is at the northern summit of the Rock. It was constructed during the Great Siege of Gibraltar, due to its advantageous position and the success of the gun at Green's Lodge Battery. It was used effectively during the Great Siege and was rebuilt during the Second World War. During the mid-twentieth century, the Ministry of Defence began to use the site as an aerial farm, which was then refurbished in 1958. The Rock Gun Battery and the Middle Hill Battery were closed to the public for decades. In 2005, the radio farm was closed and the Ministry of Defence withdrew from most of the area, transferring it to the Government of Gibraltar. However, the summit, the site of the Rock Gun Battery, continues to be under MOD authority.
==Early history==
Rock Gun Battery is in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. The artillery battery is located up the North Face of the Rock of Gibraltar, at the northern end of the Upper Rock Nature Reserve, above Green's Lodge Battery.〔 The emplacement is positioned on Ministry of Defence property, at the terminus of Rock Gun Road, on Middle Hill, at the northern summit of the Rock.〔〔
In October of 1779, during the Great Siege of Gibraltar (1779–1783), the military operations at the recently constructed Green's Lodge Battery were so successful that the British decided to establish a battery even higher on the North Face, at the summit.〔 The chosen site at Middle Hill was leveled and work was begun on a road to access the highest point of the North Face. However, the endeavour required some time, and the enthusiastic artillery gunners became impatient, not wanting to wait for completion of the new road. On their own initiative, they utilised a block and tackle system to drag a 24-pounder up the face of the Rock. After several days and much effort, they were successful. The platform for the gun was completed on 12 October 1779 and the gun was mounted on a traversing carriage. Firing from the battery began the following day. The emplacement was named Rock Gun Battery. From that elevated vantage point, the gunners were able to observe the operations of the enemy and fire upon the Spanish camp.
The emplacement was rebuilt during the Second World War by the Black Watch, and a platform for anti-aircraft guns was constructed at the edge of the North Face.〔 In the mid-twentieth century, the site shifted to one of radio transmission. In 1958, the Rock Gun radar and Middle Hill aerial transmitter site were refurbished and rebuilt. The work was undertaken by the GRISLY Squadron, more formally the Ground Radio Installation Squadron, of the Radio Engineering Unit of RAF Henlow. Rock Gun Battery was the site of 90-foot wooden towers with VHF and UHF aerials.
