It has been previously known as the GPO Tower, the Post Office Tower, and the British Telecom Tower. The main structure is 177 metres (581 ft) high, with a further section of aerial rigging bringing the total height to 189 metres (620 ft). Its Post Office code was YTOW. Upon completion in 1964, it overtook the Millbank Tower to become the tallest building in both London and the United Kingdom, titles that it held until 1980, when it in turn was overtaken by the NatWest Tower. The tower was designed by the architects of the Ministry of Public Building and Works: the chief architects were Eric Bedford and G. R. Yeats. Typical for its time, the building is concrete clad in glass. The narrow cylindrical shape was chosen because of the requirements of the communications aerials: the building will shift no more than 25 centimetres (10 in) in wind speeds of up to 150 km/h (95 mph). Initially, the first 16 floors were for technical equipment and power. Above that was a 35-metre section for the microwave aerials, and above that were six floors of suites, kitchens, technical equipment, a revolving restaurant, and finally a cantilevered steel lattice tower. To prevent heat build-up, the glass cladding was of a special tint. The construction cost was £2.5 million. ? (wiki; english)
