Hut 3

Hut 6 was a wartime section of the Government Code and Cypher School (GC&CS) at Bletchley Park, Buckinghamshire, Britain, tasked with the solution of German Army and Air Force Enigma machine cyphers. Hut 8, by contrast, attacked Naval Enigma. Hut 6 was established at the initiative of Gordon Welchman, and was run initially by Welchman and fellow Cambridge mathematician John Jeffreys. Welchman's deputy, Stuart Milner-Barry, succeeded Welchman as head of Hut 6 in September 1943, at which point over 450 people were working in the section.Hut 6 was partnered with Hut 3, which handled the translation and intelligence analysis of the raw decrypts provided by Hut 6.

Hut 8 was a section in the Government Code and Cypher School (GC&CS) at Bletchley Park (the British World War II codebreaking station, located in Buckinghamshire) tasked with solving German naval (Kriegsmarine) Enigma messages. The section was led initially by Alan Turing. He was succeeded in November 1942 by his deputy, Hugh Alexander. Patrick Mahon succeeded Alexander in September 1944.Hut 8 was partnered with Hut 4, which handled the translation and intelligence analysis of the raw decrypts provided by Hut 8. Located initially in one of the original single-story wooden huts, the name "Hut 8" was retained when Huts 3, 6 & 8 moved to a new brick building, Block D, in February 1943.After 2005, the first Hut 8 was restored to its wartime condition, and it now houses the "HMS Petard Exhibition".

A statue of Alan Turing, created in slate by Stephen Kettle in 2007, is located at Bletchley Park in England as part of an exhibition that honours Turing (1912–1954). It was commissioned by the American businessman and philanthropist Sidney Frank (1919–2006).The slate for the sculpture was selected from North Wales because the sculptor learned that Turing used to holiday there as a child and adult. The slate originated from Llechwedd, near Blaenau Ffestiniog. Turing is depicted seated and looking at a German Enigma machine. He is dressed in a jacket, but there is some deliberate untidiness in his clothing. In 2007, it was commented that the statue acknowledges Turing as a codebreaker but not as a gay icon. The statue became part of a new exhibition at Bletchley Park on Alan Turing in 2012, the centenary year of Turing's birth. Sir John Dermot Turing, nephew of Alan Turing, attended the opening of the exhibition and posed with the statue.

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. The mansion was constructed during the years following 1883 for the financier and politician Herbert Leon in the Victorian Gothic, Tudor and Dutch Baroque styles, on the site of older buildings of the same name. 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 Alan Turing, Harry Golombek, Gordon Welchman, Hugh Alexander, Bill Tutte and Stuart Milner-Barry. According to the official historian of British Intelligence, the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and without it the outcome of the war would have been uncertain. The team at Bletchley Park devised automatic machinery to help with decryption, culminating in the development of Colossus, the world's first programmable digital electronic computer. Codebreaking operations at Bletchley Park came to an end in 1946 and all information about the wartime operations was classified until the mid-1970s. After the war it had various uses including as a teacher-training college and local GPO headquarters. By 1990 the huts in which the codebreakers worked were being considered for demolition and redevelopment. The Bletchley Park Trust was formed in February 1992 to save large portions of the site from development. More recently, Bletchley Park has been open to the public, featuring interpretive exhibits and huts that have been rebuilt to appear as they did during their wartime operations. It receives hundreds of thousands of visitors annually. The separate National Museum of Computing, which includes a working replica Bombe machine and a rebuilt Colossus computer, is housed in Block H on the site.

Hut 4 was a wartime section of the Government Code and Cypher School (GC&CS) at Bletchley Park tasked with the translation, interpretation and distribution of Kriegsmarine (German navy) messages deciphered by Hut 8. The messages were largely encrypted by Enigma machines. As the Kriegsmarine operated Enigma more securely, Hut 8 had less information for Ultra than Hut 6 which handled Army and Air Force messages. Hut 4 also broke various hand cyphers and some Italian naval traffic.

The National Museum of Computing is a museum in the United Kingdom dedicated to collecting and restoring historic computer systems. The museum is based in rented premises at Bletchley Park in Milton Keynes, Buckinghamshire and opened in 2007. The building — Block H — was the first purpose-built computer centre in the world, hosting six Colossus computers by the end of World War II. The museum houses a rebuilt Mark 2 Colossus computer alongside an exhibition of the most complex code cracking activities performed at the Park, along with examples of machines continuing the history of the development of computing from the 1940s to the present day. The museum has a policy of having as many of the exhibits as possible in full working order. Although located on the Bletchley Park "campus", The National Museum of Computing is an entirely separate registered charity with its own fund-raising and separate entrance/ticketing. TNMOC receives no public funding and relies on the generosity of donors and supporters.

Hut 7 was a wartime section of the Government Code and Cypher School (GC&CS) at Bletchley Park tasked with the solution of Japanese naval codes such as JN4, JN11, JN40, and JN-25. The hut was headed by Hugh Foss who reported to Frank Birch, the head of Bletchley's Naval section. Hut 7 supplied cryptanalysts and linguists to Bletchley's front line station the Far East Combined Bureau (FECB) at Hong Kong, then Singapore, then Anderson Station (Colombo, Ceylon, now Sri Lanka), then Allidina School in Kilindini, Kenya before moving back to Colombo.Bletchley co-operated with the US Navy Code and Signals Section known as OP-20-G in Washington D.C., and with FRUMEL in Melbourne (although the reciprocal cooperation from Fabian at FRUMEL was limited and reluctant); see Central Bureau and FRUMEL.

The College of National Security (also referred to as the National College of Cyber Security) was a proposed cyber security school for 16-19 year-olds, scheduled to open in September 2020 at Bletchley Park.

St Mary's Church is the Anglican parish church in Bletchley, a constituent town of Milton Keynes in Buckinghamshire, England. St Mary's is located on Church Green Road, Bletchley.

Bletchley railway station serves the southern parts of Milton Keynes, England (especially Bletchley itself), and the north-eastern parts of Aylesbury Vale. It is 47 miles (76 km) northwest of Euston, about 32 miles (51 km) east of Oxford and 17 miles (27 km) west of Bedford, and is one of the seven railway stations serving the Milton Keynes urban area.It includes junctions of the West Coast Main Line with the Bletchley-Bedford Marston Vale Line and the disused Bletchley-Oxford Varsity line. It is the nearest main line station for Bletchley Park (the World War II codebreaking centre and modern heritage attraction) and Stadium MK (the home of Milton Keynes Dons F.C).

Lord Grey Academy (formerly Lord Grey School) is a comprehensive 11-19 coeducational secondary academy and sixth form in West Bletchley, Milton Keynes, England. Previously a grant-maintained foundation school and specialist language and humanities college, the school academized on 1 April 2018 under the sponsorship of the Tove Learning Trust. It was created from the amalgamation of the Bletchley Grammar School and Wilton County Secondary School in 1973, opening on the site of the latter. From 2011 to 2014 the school operated, in partnership with Sir Herbert Leon Academy, the Milton Keynes South Sixth Form. Although this sixth form was discontinued the school still provides sixth form education independently.The school was last graded by Ofsted as good and was previously requires improvement, satisfactory and inadequate. The school is larger than average with a population of 1449 pupils, of which 51% are girls and 49% are boys. 35.3% of students are eligible for free school meals and 17.9% speak English non-natively.

The Bletchley Flyover is railway viaduct that crosses the West Coast Main Line (WCML) just south of Bletchley railway station in Milton Keynes, England. It was originally a reinforced concrete railway viaduct that carried the former Varsity line between Oxford and Cambridge from 1959 until its closure in 1968. The flyover was retained, but largely unused until 2021, when the East West Rail Alliance demolished then rebuilt the structure. It reopened for engineering use in early 2022.
