This is a rare chance to see the best views in London at the top of BT tower! This space used to be Top of the Tower — a rotating restaurant on the 34th floor that would make one revolution every 23 minutes. This iconic landmark was opened in 1965 and was the place to be for the socialites of that swanky era, with famous diners including The Beatles and Muhammad Ali. The restaurant closed in 1980 and is still closed to the public today. At 581 feet, it was the tallest building in the United Kingdom until 1980 when the NatWest Tower was completed.
