When you reach the co-ordinates, you will notice a large security gate and guardhouse across the road. This is Mytchett Place which is now privately owned and you cannot enter. It is now owned by a company making electric vehicles. However, it is the reason for the location of this cache.
Mytchett Place is apparently haunted. According to a report in the Psychic News there are numerous reports of figures moving up and down the staircase, lights going on in locked rooms and photographs moving inexplicably.
However, what is probably more haunting about Mytchett Place is that for a year during World War 2, it was known as Camp Z, and was home to one of the most infamous Nazi Prisoners of War: Rudolf Hess.
On May 20, 1941, Rudolf Hess was transported from the Tower of London to Camp Z which was at Mytchett Place. This had been specially set up for his arrival with heavy security and bugging devices. He failed to commit suicide on June 15 1941 after throwing himself off a balcony.
But Hess was moved on June 26th 1942 to Wales, after Polish Soldiers tried to storm Mytchett Place and kidnap Hess as revenge for attrocities taking place in Poland. Very few details have made public except a MI5 file released in 1999 that confirms a gunfight between Polish Soldiers and the guards at Mytchett Place
Because the roads are surprisingly busy, you can't stop next to the cache. I recommend parking in Grayswood Drive or The Basingstoke Canal Center off of Mytchett Place Road. Either will result in walking along stretches of road with no pavements (Grayswood Drive route is better), so be aware if you are caching with small children or dogs to take extra care. Doing so should get you to the cache within 5-10 minutes
NOTE: Some GPS systems show Mytchett Lake Road as One-Way when it isn't. It also has signs up as an MOD road but don't worry about driving down here, just take care going over the single lane bridge, as not all traffic gives way when it's supposed to!
