The Post Office Tower (later British Telecom Tower) was built in the early 1960s on commission by the General Post Office to be used to carry groovy signals across London. It raises almost 180 meters over the ground and once had both a observation deck, cocktail bar and a restaurant at the top. Sadly, the observation deck was closed down in 1971 after a bomb exploded in the mens toilet and the restaurant was closed in 1980 leaving London without any revolving restaurant that can be found in most big cities around Europe. If you want to view London from above today, the London Eye offers a spectacular view. The embedded movie below was made around the opening of the tower and takes you on a kitsch and interesting tour around it.
