Admiralty Tunnel is a tunnel in Gibraltar.〔Eley, Colonel D.M. (1957). ''The Gibraltar Tunnels''.〕 The tunnel was used for the purpose of bringing stone from the east side.〔(【引用サイトリンク】title=The Gibraltar Tunnels )〕 During the second World War the tunnel contained an operations centre where Dwight Eisenhower planned Operation Torch. The operations centre is now (2013) used to house a secure data facility. ==History== The new navy base was begun in 1893 but for some time the stone was brought by barge from the east side of the rock to Gibraltar Harbour on the west side. The tunnel allowed bringing stone from the quarries on the east side to be brought via a one metre narrow gauge railway to help constructed the navy base on the west side.〔 It is the only tunnel that runs from east to the west of the Rock of Gibraltar and during World War Two the tunnel was reworked and a 3,000 square metre area roughly half-way down it became a state of the art communications centre. This Allied Command Headquarters centre was protected from enemy bombs by metres of rock in every direction and contained the board room where the invasion of North Africa (Operation Torch) was planned〔 by Dwight Eisenhower. As a result Eisenhower not only commanded the operation but he was the first non-British person to command Gibraltar for 200 years.It had its own systems for fresh air, electricity, lighting and communication links to the outside world. The space now contains a very secure data storage facility * previously owned by Vault Technology Services〔(【引用サイトリンク】url=http://www.ggpe.gi/visit-to-secure-data-storage-facility/ )〕 and now operated by ''Continent 8''.〔(Directions to ... ), Continent 8 Technologies - Gibraltar, accessed April 2013〕 It is not open to the public but it is possible to see from one end to the other and thus to observe how straight the tunnel is. The west end of the tunnel is accessible from Queensway.〔 *Size of Data storage facility is 3000m2 which is split up into 80 separate rooms. 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「Admiralty Tunnel」の詳細全文を読む スポンサード リンク
