The tunnels of Gibraltar were constructed over the course of nearly 200 years, principally by the British Army. [1] Within a land area of only 2.6 square miles (6.7 km 2), Gibraltar has around 34 miles (55 km) of tunnels, nearly twice the length of its entire road network. The first tunnels, excavated in the late 18th century, served as ...
The Great Siege Tunnels in the British Overseas Territory of Gibraltar, also known as the Upper Galleries, are a series of tunnels inside the northern end of the Rock of Gibraltar. They were dug out from the solid limestone by the British during the Great Siege of Gibraltar of the late 18th century.
The Strait of Gibraltar crossing is a hypothetical bridge or tunnel spanning the Strait of Gibraltar (about 14 km or 9 miles at its narrowest point) that would connect Europe and Africa. The governments of Spain and Morocco appointed a joint committee [ 1 ] to investigate the feasibility of linking the two continents in 1979, which resulted in ...
The Great North Road is a large road tunnel in the British Overseas Territory of Gibraltar. It was constructed by the British military during World War II inside the Rock of Gibraltar and remains property of the Ministry of Defence to this day. The road allowed lorries to travel from the north to the south of Gibraltar entirely within the Rock.
The Gibraltar Tunnel is proposed to be a rail tunnel linking Africa and Europe. A tunnel would likely be an electrified rail tunnel with car shuttles due to the depth of the Strait of Gibraltar (up to 900 metres (3,000 ft)) and the length of the tunnel making it a great challenge to remove vehicle exhaust. Similar considerations led to the ...
An aerial view of modern Gibraltar, looking north-west. The nature and position of Gibraltar's defences have been dictated by the territory's topography.It is a long, narrow peninsula measuring 5.1 kilometres (3.2 miles) by 1.6 kilometres (1 mile) wide at maximum, with a land area of about six square kilometres (2.3 square miles).
It is one of two tunnels in Gibraltar named after Lt Col A R O Williams, of 178 Tunnelling Company, Royal Engineers. Arthur Robert Owen Williams (1905-1989) was known as "ARO". He had trained as a miner in South Africa and was in charge of tunnelling operation in Gibraltar during World War II. When he left the army he was also given an OBE. [1]
Inside the Rock of Gibraltar itself, miles of tunnels were excavated from the limestone. Masses of rock were blasted out to build an "underground city". [ 4 ] In huge man-made caverns, barracks, offices, and a fully-equipped hospital were constructed, complete with an operating theatre and X-ray equipment .
