Bletchley Park, also known as Station X, is an estate locate in the town of Bletchley, in Buckinghamshire now part of Milton Keynes, England. During World War II, Bletchley Park was the location of the United Kingdom's main codebreaking establishment. Codes and ciphers of several Axis countries were deciphered there, most famously the German Enigma. The high-level intelligence produced by Bletchley Park, codenamed Ultra, is frequently credited with aiding the Allied war effort and shortening the war, although Ultra's effect on the actual outcome of WWII is debated.
