The Post Office Tower

gpotowerfi - The Post Office Tower

Today is the anniversary of the topping out of the BT (or Telecom) Tower and for some its still known as the Post Office Tower. Besides the images showing early designs for the tower itself, the structure was going to be known as the Museum Radio Tower. The rather grandiose name came from the fact the site of the new building itself was part of the Museum Telephone Exchange on the corner of Cleveland and Howland Streets.

Picture of the tower I took a couple of days ago.

The tower had four opening ceremonies and that in July 1964 was only undertaken at the insistence of the then Postmaster General J. R. Bevins. He wanted to show the world the new tower was led by the Post Office and not the Ministry of Public Buildings and Works, who were its actual designers.

However the GPO’s Chief Public Relations Officer, T. A. O’Brien, said there was little point organising events before any equipment had been installed, “….we would only make ourselves look silly if we tried to organise a ceremony which would have no meaning whatever.”

Our crane operator, Jimmy Wheelan, would have been able to see parts of the Victoria Line being constructed during his working hours. This would include the ongoing works at Euston, the nearby Great Titchfield Street shaft and the works in Cavendish Square.

A Different Tower

The initial plans for what became the Post Office Tower were totally different to what was eventually designed. In these early plans it was always intended the new tower would be around five hundred feet in height.

A tower had been mooted as early as 1957. Up to that point a series of radio masts ad been considered but deemed not high enough in view of the new skyscrapers then being proposed in London. Those initial plans were quite radical compared to what was eventually produced, being more in the style of those towers found elsewhere around the world. Eventually a sort of Britishness design was drawn up, no doubt helped by the fact the new tower had to be extremely rigid and the reason for its cylindrical shape.

The designers for the new Museum Radio Tower were Eric Bedford and G. R. Yeats, and work began on the structure in June 1961. Bedford says ‘My idea was, if it’s a tower it should be as tall and slim as possible. We kept trying to slenderise the structure.’ This explains why the earlier plans were rejected in favour of a cylindrical structure.

The name had during 1963 certainly become the GPO Radio Tower before further changing to the G.P.O. Museum Tower. However reports and publications were still using the old names in 1965, the year the tower was opened.

The GPO itself had an internal competion among staff to find out any preferred names that might be used for the tower. Among these were Pointer, Spindle, Liaiser and Telebeacon!

As has been mentioned earlier, the tower wasn’t planned to be as high, however tall skyscrapers were becoming the forte in early sixties London (there were surprisingly quite a few being planned or under construction – for example Centre Point, Shell Centre, St Helens Tower) thus it was decided to alter the design and make it even higher. The original height for the Museum Radio Tower seems to have been planned at 498 feet high (or 507 feet as some sources claim.)

These other new buildings going up in London would clearly affect the radio transmissions from the new tower. Centre Point was just under four hundred feet however it would have been sufficient to affect the transmitters on the new Museum Radio Tower.

The plans for Centre Point had been approved in 1959 thus the Ministry of Public Buildings and Works’ designers for the new GPO tower were in fact a little behind with their own plans! I think perhaps they soon realised the number of new skyscrapers being proposed would affect their own plans, so up they went!

The top most of the transmitter galleries were to be 362 feet in the original plans for the Museum Radio Tower, so it was obvious the design would have to be altered considerably.

What happened is the galleries, instead of topping out at 362 feet, would in fact begin somewhere above that earlier height and this would rise as far as around 470 feet where the lowest of the observation platform would begin.

The picture below shows a newer version with the top bit being the observation and radio receiver galleries. The earlier mast has now been changed.

A model of the same tower with the current tower’s structure visible ((except there’s sixteen instead of the fifteen lower floors that were built) in the entire model from bottom to where the present aerial galleries are.

In the final design that bit was moved higher upwards and the galleries and restaurant given their own exclusive domain on top of that newly extended section. And that mast from the earlier plans was used too.

In these pictures it can be seen the styling that forms the bottom part of the Telecom Tower had already been decided in these plans. In the next picture the top of the tower has been increased and a different style of mast added to the topmost section.

What happened is the designers put a new bit on top of this earlier design, and used the space left vacant for the aerials and transmitter dishes.

How the older and newer designs compare.

The original plans accounted for sixteen floors in the main section. This was reduced to fifteen in the final construction, with the lower of these floors being replaced by a substantial concrete collar (as engineers call it) to give the entire tower even more rigidity. The tower’ stability was ever so important if any of the radio or microwave transmitters were to work effectively.

The height of 620 feet seems to have been agreed upon in either late 1961 or early 1962.

When exactly it became the Post Office Tower I do not know, it was probably in 1965 when the then Prime Minister Harold Wilson officially opened it.

The official name was the General Post Office Tower (G.P.O. Tower in short as some sources do cite) so its was simply a means of making the building slightly more public conscious. Nevertheless a number of media sources were still at this time calling it the Museum Radio Tower!

Some 1965 first day covers call it the Post Office Communications Tower!

Throughout the seventies and eighties official sources continued to use the G.P.O. Tower so it was a matter of personal preference really which name was used for the tower. Personally I still call it the Post Office Tower but when referring it to others it becomes the BT or Telecom Tower!

The tower in 1966 clearly showing the different design stages. This tells us the lower section was designed (and the panels, cladding,) bought earlier than the upper section, which had to constitute a completely new manufacturing stage, including the revolving restaurant – for which new contracts had to be put out.

In Design Magazine for 1980, written upon the advent of the new name of BT Tower (this being a result of the public authority, the GPO, becoming British Telecommunications or in short BT, in readiness for privatisation.) The author commented it would be a hard sell to have the name accepted by the public, ‘especially as most people still call it the G.P.O. Tower.’

Although the tower’s design is credited to Eric Bedford all the references to Bedford don’t even show a single picture of him. Was he an elusive guy I wondered? I sourced a couple of pics at Getty’s of which here’s one. Its clear from these pictures Eric Bedford had designed all the special illuminations and decorations for the 1953 Coronation.

How high is the tower? Everyone says 620 feet which is right of course however the total includes that forty foot mast plonked right at the top of the tower. The official height of the building itself is 580 feet (or 580.4 feet) to be exact.

The above image is a photomontage created from the pages of the Post Office Tower book, which I bought probably on my third visit up the tower, that being the one without an adult to supervise me, it was about 1966/67.

I have previously offered the whole book in pdf format including a large spread of the panorama pages. I spent ages creating this pdf version and it was available on the blog for about three years – sadly only a handful of people ever downloaded a copy, thus decided there was no demand for it and removed it.

Sharing is caring!

  • Well I found this article very interesting, was only 6 months old when they opened it. I have never got to go up it sadly, nor had a meal in the revolving restaurant but keep googling it from time to time. Thanks for taking the time to write and post this
