The giant cogwheel, thought to be a gun emplacement some time ago, was part of the driving mechanism for the whirling arm at the former Admiralty Research Establishment. Part of some kit used to create conditions in a toroidal water tank to test torpedos and other weapons. One of the reasons Teddington’s National Physical Laboratory was a prime target during WW2. This relic is now tucked away in Bushy Park partially forgotten. In the area known as Donkey corner, Hampton Hill end.
In 1944 Bushy Park became Camp Griffiss, General Eisenhower’s SHAEF headquarters. It was a large base with tennis courts, two bowling alleys, a swimming pool and a small airstrip. It was one of the assembly points prior to D-Day. Only the tennis courts survive. Bombed out locals squatted the camp immediately after the war. Royal Parks wanted their park back, so the facilities were bulldozed.
