:''for the battery in Watson's Bay see Signal Hill Battery'' Signal Hill Battery or Signal Battery was an artillery battery in the British Overseas Territory of Gibraltar. The battery was mounted high on the rock. Little remains today as the Gibraltar Cable Car top station was built on the site of the old battery. ==History== The top of the Rock of Gibraltar is a natural site for a signal station and the high Signal Hill has had a Signal Station since at least 1727. In 1773 it had its first 6-pounder gun installed.〔 The added height gave the gun an extra range and it could also fire in any direction. However, in Gibraltar height can be a disadvantage as the levanter cloud can remove the gunners visibility. 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.〔(【引用サイトリンク】url=http://www.discovergibraltar.com/pages/mainlogo/mainfrm.htm )〕 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.〔 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Signal Hill Battery, Gibraltar」の詳細全文を読む スポンサード リンク
