During World War II this country estate was the headquarters of a code-breaking project named ULTRA. This was a huge triumph for British Intelligence; they broke nearly all the codes used by the Germans and Italians and read most of their supposedly secret communications throughout the war. This was of enormous value to Allied commanders.
Arguably the Colossus machine — built at Bletchley to crack the Lorenz cipher used by parts of the German army — was the first programmable digital computer. Certainly Alan Turing — a Cambridge mathematician who was a key code-breaker during the war — made large contributions to the theory of computation before the war, and to both theory and practice after it. Several other ex-Bletchley people also became computer pioneers in the postwar years
The historic value of this site has now been belatedly recognised in the form of a museum with a significant number of things to do for both adults and children.
Bletchley Park is an English country house and estate in Bletchley, Milton Keynes (Buckinghamshire), that became the principal centre of Allied code-breaking during the Second World War. During World War II, the estate housed the Government Code and Cypher School (GC&CS), which regularly penetrated the secret communications of the Axis powers – most importantly the German Enigma and Lorenz ciphers. The GC&CS team of codebreakers included John Tiltman, Dilwyn Knox, Alan Turing, Margaret Rock, Mavis Lever, Harry Golombek, Gordon Welchman, Hugh Alexander, Donald Michie, Bill Tutte and Stuart Milner-Barry.

Bletchley Park is home to the National Museum of Computing. Only the Colossus Galleries of the NMC are open 7 days per week; the full museum is open most weekends and some weekdays.
The Dons were promoted in 2026 and now play soccer in League One, the third tier. They play at Stadium MK, capacity 30,000, two miles southeast of the railway station.
Indoor activity venue with a large karting circuit that hosts the British Rental Kart Championship, together with axe throwing, escape rooms, virtual clay shooting and food and drink options. A good choice for groups, families and corporate events. Advance booking is recommended, especially for karting and larger groups.
Milton Keynes Bowl
Known for international artists, this amphitheatre regularly hosts live music events.
A giant dome, home to a 16-screen cinema and Snozone, the largest indoor ski slope in the United Kingdom.
Billed as the country's "most popular" since it has the most people attending for any theatre in the country. Travelling shows and longer running productions are staged here, often large productions will come here as a final dry run before they take their shows to London's West End.
