Ultra
The British government established a code-breaking effort, known as Ultra, at Bletchley Park in Buckinghamshire, England, during World War II.
The Ultra intelligence project was based at Bletchley Park, a British government cryptological establishment located in Buckinghamshire (now in Milton Keynes), England.12
Situated approximately 50 miles northwest of London, the site served as the wartime headquarters for the Government Code and Cypher School (GC&CS). During World War II, the facility—which included a Victorian manor house and numerous wooden outbuildings—housed the code breakers, including Alan Turing, who worked to decrypt messages from German Enigma and Tunny cipher machines.12
