Radio City Tower (also known as St. John's Beacon) 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 125 metres (410 ft) tall, and is the second tallest free-standing building in Liverpool and the 32nd tallest in the United Kingdom. When considering the height of the building, it has a 10m long antenna on the roof, making it the tallest structure in Liverpool (including antennas). As testament to the importance of its design, which was described by Historic England as “embodying the technological bravura and spirit of the space age”, the building was listed at Grade II in November 2020.
