Radio City Tower is a radio and observation tower in Liverpool, England, built in 1969 and opened by Queen Elizabeth II. It was designed by James A. Roberts Associates in Birmingham. It is 138 metres tall, and is the second tallest free-standing building in Liverpool and the 32nd tallest in the United Kingdom.
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. On Saturday 23 April 1977, there was a sponsored abseil from the viewing level of the tower. It was done as part of the celebrations associated with the Silver Jubilee of Queen Elizabeth II in that year. It was done by Birkenhead-based group, The Peninsula Outdoor Pursuits Club with some assistance from others. The abseil, and an earlier practice session were filmed for BBC Look North (the Manchester-based predecessor to North West Tonight), with BBC reporter, Alistair Macdonald, who abseiled, both in the practice, and also in the full descent. Details of the practice were broadcast on Tuesday 19 April, and the descent itself was broadcast on Monday 25 April 1977.
