Impact and Legacy

Bletchley Park was vital to Allied victory in World War Two.

The Government Code and Cypher School (GC&CS) devised methods to enable the Allied forces to decipher the military codes and ciphers that secured German, Japanese, and other Axis nation’s communications. This produced vital intelligence in support of Allied military operations on land, at sea and in the air. 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 expertise developed at Bletchley Park was taken forward in the organisation known now as the Government Communications Headquarters (GCHQ). This highly efficient intelligence-gathering machine is aided by the special relationship with America, the genesis of which came from collaboration at Bletchley Park. Today Bletchley Park is a heritage site designed to preserve the uniquely important story of these Codebreakers during WW2.
