  • Originally known as the Post Office Tower, it was the UK's highest building at the time, standing 189 metres tall including a 12 metre London Weather Centre radar mast.

  • The tower was designed to meet the increased demands of broadcasting by allowing the use of microwaves instead of landlines for transmitting television signals.

  • Today the tower handles around 3,000 switched calls per day, 99 per cent of all live football and terrestrial television passes through it and it is a Grade II listed building.
