      Re: "resembling a gigantic Star Trek gadget"

      The then brand-new Post Office Tower (as I will always call it) starred in the Doctor Who story, The War Machines - where it hosted an evil supercomputer. Hold on... Joe wasn't allowed into some parts of the building.

      I bloody love that tower. For something quite so big it does hide itself quite well at street level, you only get the occasional glimpse until you're really quite close and then it is towering over you.

    it's really interesting to find out a bit about something as iconic as the BT tower. Just one thought though... the £3.28 admission fee would be nearer £50 these days if you add inflation into the mix.

      Re: £50

      I don't have to hand how Joe calculated that figure, but according to the National Archives, 1965's 4 shillings = 2005's £2.57. So Joe's £3.28 isn't far off the mark.


      1. Chris Miller

        Re: £50

        I think Joe used the same BoE site; £1 in 1965 equates to £16.39 in 2012 money, so four bob (20p) equals £3.28. My first legal pint (c. 1970) cost 1/11 so I could have got two pints for the cost of the trip up the Tower, whereas £3.28 will barely buy you a pint in London today.

          Re: £50

          4/- (£3.28) feels right - we went up the Tower not long after it opened. As a schoolboy on our radio club's annual coach visit to London for the RSGB Exhibition - that would have felt affordable for a special treat. My weekly pocket money then was 1/- (5p). The Tube fares were still only old coppers to shuttle between the war surplus junk shops in Tottenham Court Road, Praed Street, and Edgware Road. In Proops I bought a short length of that new magic material - fibre optic cable.

          When walking along Greek Street and Lisle Street the older members of the club formed an outrider escort to shield the teenagers from the strip club touts and the ladies standing in doorways .

          A trip up Monument costs something like £3:50 at the moment, and gives a fantastic view out over London. Unfortunately there are no high speed lifts to wisk you to the top, it's 311 steps!

          I believe you can visit the Bar at the top of Tower 42 (the Natwest tower) for the price of a drink, thus the pint glass icon.

            The main reason to avoid the Shard, as well as the BT Tower and to a lesser extent the Wheel (although that is good to go on) is because you want to see them, they are part of the skyline,

            I suggest something like the Heron Tower, it’s got a bar at the top

      £3.28 IS the inflation-adjusted price. The original price was 4 shillings, i.e. 20p.

    tall buildings

    A fair few of London's tall buildings are clustered together but the best views can be had from the isolated ones.

    I was fortunate enough to go up Queens Tower at Imperial College (all the way to the roof unofficially) and the views were amazing. Both should be preserved as iconic in their own way.

      Re: tall buildings

      Despite being scared of heights I've been on top of Millbank Tower, BBC East Tower (next to TVC), Barbican Tower, Swiss RE (Gherkin) and The Shard (*cough* didn't pay *cough*). But I've never made it all the way up BT Tower despite having visited the broadcast facilities more times than I dare to count.

      The Shard is very impressive, more so for looking down than for looking across.

      BBC East Tower was (at the time) more isolated than most and intriguing to see the vista.

      The Gherkin might be architecturally special but the view is modest in the context of the surroundings.

      Millbank Tower is most interesting for its neighbours

      Barbican: the roof layout doesn't help those of us who are scared of heights.

    As an American...

    I was impressed when I first saw BT tower from the streets of London. I have seen many comms towers in the US, but nothing as practical looking as this multi-use structure. I'm surprised we don't see more comms equipment on large buildings in the US. There are some, but I feel there is a missed opportunity for some architectural aesthetic value. I think BT tower would fit in with any of our major cities.

      Re: thanks!

      There was revolving restaurant in Cape Town in 1973. It was not very high and the rotation not very smooth. The locals' dining technique was to pile up all three courses from the buffet on the first visit. Anyone approaching it sequentially found very little left for 'seconds' or dessert. The best view in town was of course from the top of Table Mountain - if it wasn't cloudy. The cafe at the peak served a decent toasted cheese sandwich.

      A memorable "high" dinner was in Stockholm. A gantry perched on top of a cliff overlooking the main harbour. The entertainment was the bird's-eye view of a Finland ferry docking. The first few passengers staggering walking down the short gangway collapsed before they reached the quay. They weren't called "booze cruises" for nothing.

    London - same old, same old: Paris the historic past preserved

    London has been abused; it's skyline a momumental hodge podge of buildings of many heights. London is no longer remarkable, it is simply a copy of so many other world cities.

    Paris has restricted the unfettered littering of the skyline, restricting highrises to well defined areas.

    Most of Paris's high-rise buildings are located in three distinct areas, which are: La Défense, located in the western inner suburbs in the département of the Hauts-de-Seine; Italie 13, located in the southern half of the 13th arrondissement; Front de Seine, located in the 15th arrondissement.

    London? Just wanton desecration, pure sacrilege.

    I don't get the reasoning of the headline

    I mean sure, microwave links become a niche, though I'm surprised they actually removed all those dishes, just giving those spaces to radio hams and Freifunk enthusiasts would put it into good use.

    However it's current use to the BT is completely independent of its shape. It's a building, it got sensible amounts of fibre to it, it has a generator so they use it for backend broadcast systems. Of course it's a serious decision, but would it have been an office building with the same infrastructure, they would have taken that one.

    So yes it's a relic even though they still get some use out of it.
