The BT Tower

One of the most famous landmarks peering over the skyline of the Bloomsbury area is The British Telecom Tower. Owned by the BT Group, it has been previously known as the Post Office Tower, the London Telecom Tower and the British Telecom Tower. The main structure is 177 metres (581 feet) tall, with a further section of aerial rigging bringing the total height to 189 metres (620 feet). 

Today it is not open to the public.
