BT Tower
Eric Bedford and G. R. Yeats, 1965
An enduring, distinctive feature of the London skyline for the last 54 years, this is a rare opportunity for members of the public to visit the famous revolving floor, 158m above the capital...
The BT Tower was designed by the Ministry of Public Works under the direction of Chief Architect Eric Bedford. The senior architect involved in the project was Mr G R Yeats and the main contractors were Peter Lind & Co Ltd.
Construction began in April 1961 and was completed some four years later, opening for operations on 8th October 1965 by the then Prime Minister Harold Wilson.
As construction began a borehole survey of the site revealed a tricky problem. There was hard chalk – suitable for supporting the foundations – beneath the blue London clay, but it was 53 metres down and therefore an alternative way of supporting the 13,000 tonne structure was needed.
An Italian firm came to the rescue, laying a concrete raft on the clay, some eight metres below ground level. The raft measures around 27 metres square, is one metre thick and reinforced with six layers of steel cables. On it sits a seven metre tall reinforced concrete pyramid with a flat top. The raft and pyramid together provide the foundations and, on top of them, a hollow reinforced concrete shaft runs from near enough ground level, right up through the centre of the tower. This is the backbone of the whole structure which, together with a collar connecting it to the adjacent four-storey building, gives the Tower its stability.
A climbing crane was used to build the Tower; this was later dismantled and lowered from the top by its own winch.
As with other tall buildings, the structure expands and contracts as the temperature changes. This means that in winter the Tower can be as much as 23cm shorter than it is in the summer.
The revolving floor had to be prefabricated and hoisted up in sections, there is a three millimetre clearance between the revolving and stationary sections of the floor and yes, it still revolves today. Two high-speed lifts transport visitors to the upper levels of the Tower, taking just over 30 seconds to reach the top.
Amazingly the Tower was – until 1993 – classified as an ‘official secret’ despite its obvious presence on the London skyline. In November 2001 English Heritage declared the Tower a national monument and in 2003 it became a Grade II listed building.

Among the geologists who subsequently paid brief visits to Crater Lake, there were a few who found it difficult to accept Diller's interpretation of the "backflow," and some entertained the idea that faulting on the caldera wall might in some way offer an explanation. Allen, however, was the first to understand the relations correctly. He saw that if the "backflow" is regarded as an "upflow," in other words as the actual feeder of the Cleetwood dacite, all difficulties disappear. The lakeward dip of the lava on the wall does not mean movement in that direction, but exactly the reverse. When the summit of Mount Mazama collapsed, the bounding fracture sliced across the inclined conduit of the Cleetwood flow.
However in the book, Crater Lake the Story Behind the Senery, The authors still insist that "Mazama Rock (foreground) was formed late in Mount Mazama Life. Lava flow patters are preserved in the rock. Note the rubble on top and vertical joints produced when lava oozed back into the caldera." Picture Caption Page 11; Another Picture Caption on Page 15 makes the same assertion.
USGS Scientific Investigations Map 2832 has the following quote: "tongue of lava descending to lake edfe is rhyodacite of the Cleetwood flow, remobilized from the pasty interior of the lava flow after the caldera collapsed.
