The* BT Tower* is a grade II listed communications tower located in Fitzrovia, London, owned by BT Group. It was also known as the GPO Tower and the Post Office Tower.
It was later officially renamed the Telecom Tower.
The main structure is 581 feet (177 m) high, with a further section of aerial rigging bringing the total height to 620 feet (189 m).
Upon completion in 1964, it overtook the Millbank Tower to become the tallest structure in London until 1980, when it in turn was overtaken by the NatWest Tower. It was opened in 1965 by Prime Minister Harold Wilson who viewed it as a monument of a Britain shimmering in the "white heat of technology".
A 360° coloured LED screen is located near the top of the tower—making it a conspicuous presence on the London skyline—which displays news events to the public across central London every day, including breaking news
BT Group owns at least 200 radio masts and towers in Britain. Of these, fourteen are reinforced concrete towers. The rest are of steel lattice construction.
Seven of the fourteen are of similar design, known as the 'Chilterns' type, after the first one which was built at Stokenchurch on the Chiltern Hills.
