Signal Hill Battery, Gibraltar

Remains of the Signal Station just south of Signal Hill Battery

The top of the Rock of Gibraltar is a natural site for a signal station and the 1,200 feet (370 m) high Signal Hill has had a Signal Station since at least 1727. In 1773 it had its first 6-pounder gun installed.[2] The height above sea level gave the gun extra range and it could also fire in any direction. However, in Gibraltar height can be a disadvantage as the levanter cloud can interfere with the gunners view of targets.

By 1892 the gun had been updated to a BL 6 inch QF gun mounted on a Vavasseur mounting. Seven years later a second gun was added and after two more years there were four 6 inch guns and two QF 12 pounder 12 cwt gun. The latter two had depression mountings allowing them to be fired down the side of the Rock but they were removed by 1906.[2]

Remains of old cable car at Signal Station.

During World War II the Rock was a target for air raids and two 3 inch 30 cwt anti-aircraft guns were mounted on the hill together with a Bofors 40 mm gun.[2]

The battery was later removed and built over by the Gibraltar Cable Car top station, however there are remains of an earlier cable station that was used to bring supplies (or a brave man) up to the top of Signal Hill. Besides the remains of earlier military buildings there is also a short tunnel that runs east to west.[2]

Under the battery is a tunnel which still (2013) contains the remains of accommodation that was installed for the gunners of the battery. The tunnel which runs from east to west contains a hollowed out interior which is six by twelve metres. Within this space are the remains of a Nissen hut. The small tunnel also contains cooking and other abandoned facilities.[2]
