Bletchley

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.

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).

Bletchley and Fenny Stratford is a civil parish with a town council, in Milton Keynes, Buckinghamshire, England. It was formed in 2001 from the unparished area of Milton Keynes, and according to the 2011 census had a population of 15,313. Together with West Bletchley, it forms the Bletchley built-up area.The parish includes Brickfields (includes the Blue Lagoon), Central Bletchley (that is, Bletchley east of the West Coast Main Line), Denbigh (Denbigh North, Denbigh East and Denbigh West), Fenny Stratford, Fenny Lock, Granby, Mount Farm and Water Eaton (includes "Lakes Estate").

The Bletchley Leisure Centre is an indoor leisure facility in Milton Keynes, Buckinghamshire, England. The new Bletchley Leisure Centre opened in 2009 replacing the original centre. The original centre opened in the 1970s replacing the outdoor queens pool. The centre was quite iconic with its pyramid building that housed the pool. Until the 1990s it also had a multi-storey car park with a snake-like walkway leading from the carpark to the centre reception. The old centre and duck pond were demolished and the site was cleared for the new leisure centre and a new multi storey car park. Some groups tried to get the pyramid building listed to prevent demolition. The old centre housed a 907-seat capacity sports hall which was the home of professional basketball club Milton Keynes Lions. The Leisure Centre has been home to the Lions basketball team since 1998, when the Hemel Hempstead Royals later Watford Royals relocated here. The Milton Keynes Lions had planned to move into Arena:MK, a new 4,500-seat arena at the stadium:mk site in Denbigh, Milton Keynes, before the start of the 2008-2009 season. However, completion of this arena has been delayed due deferral of proposed commercial developments around the site (which would have funded the build). The Lions original home in Bletchley became scheduled for demolition, leaving the club searching urgently for a new base. Subsequently, the Lions obtained agreement to play their home games in Middleton Hall in Central Milton Keynes. The Lions subsequently moved to a warehouse in Grafton Gate, having converted it into a 1,400-seat basketball arena and practice venue.

Bletchley TMD is a railway traction maintenance depot situated in Bletchley, Milton Keynes in Buckinghamshire, to the north east of Bletchley railway station, on a siding off the Marston Vale line. The depot is operated by London Northwestern Railway.

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.

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.

The Blue Lagoon Local Nature Reserve is a Local Nature Reserve in Bletchley, Milton Keynes in Buckinghamshire, United Kingdom. The Blue Lagoon is the only Local Nature Reserve in the City of Milton Keynes. The diverse habitat, including shallow and deep water, grassland, scrubland and woodland, hosts an abundance of fauna and flora. The Blue Lagoon is also extensively used as a recreational facility.

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.

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".

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.
