The transmitter block seen from one of the concrete plinths of tower 3. In December 2004 the earthen traverse surrounding the building was lowered in height to stop children from jumping onto the roof and the entrance doorways were bricked up.

"Chain Home" was the codename for a ring of coastal radar stations built before and during WWII. The system is otherwise known as AMES Type 1. It was devised by Sir Robert Watson-Watt's Air Ministry research station near Bawdsey, Suffolk, and consists of radar fixed on top of a radio tower mast called a 'station' to provide long-range detection of aircraft. The Chain Home stations were arranged around the British coast, initially in the South and East but later the entire coastline, including the Shetland Islands. The system was dismantled after the war, but some of the tall steel radar towers were converted to new uses > Link. Link
