St. John’s Beacon (1969 – 1999)
Near the top of the tower was a revolving restaurant, the facade and floor of the restaurant revolving as one unit, while the roof of the restaurant was used as an observation platform for visitors. There are 558 stairs up to the top, and two lift shafts which reach the top in 30 seconds.
The tower is structurally independent of the adjacent shopping centre, with a simple foundation onto sandstone. The foundation is 60 feet in diameter, 17 feet deep and begins 40 feet below Houghton Street. It has a tapering shaft that was built using slip-formed concrete. The crows nest structure at the top was then added after the shaft was formed.
Radio City Tower (1999 – present)
The tower was refurbished in 1999 at a cost of £5 million. It reopened as Radio City 96.7 (and Magic 1548) in August 2000.
