History of Bletchley Park

Bletchley Park rejoices in the fact that, until fairly recently, it was probably Britain’s best kept secret. This is because the secrecy surrounding all the activities carried on here during World War Two was of vital importance to our national security and ultimate victory.
 
It was here that an organisation called the Government Code and Cypher School (GC&CS) studied and devised methods to enable the Allied forces to decipher the military codes and ciphers that secured German, Japanese, and other Axis nation’s communications. The result of which was the production of vital intelligence in advance of military operations. Bletchley Park also heralded the birth of the information age with the industrialisation of the codebreaking processes enabled by machines such as the Turing/Welchman Bombe, and the world’s first electronic computer, Colossus.
 
At the end of the War the remarkable expertise that had been developed at Bletchley Park was taken forward by a number of the wartime GC&CS staff in a new organisation known to this day as Government Communications Headquarters (GCHQ). This highly efficient intelligence-gathering machine was, and still is, aided by the special relationship with America, the genesis of which came from collaboration at Bletchley Park, that burgeoned through the Cold War and continues today.
