Another fun fact - it had a rotating restaurant on the 34th floor called The Top of the Tower, which was operated by Butlins, and made one revolution every 23 minutes, but was closed in 1971 following a bombing[0]. Apparently there was talk of reopening the restaurant for the London Olympics in 2012 (not clear whether it would have rotated or not) but this didn't happen. Will be interesting to see if the hotel gets the rotating restaurant working again after all this time.
