Hut 8

Hut 8 is a listed codebreaking facility in West Bletchley that now forms part of the Bletchley Park museum. The single-story rectangular structure extends 155 feet (47 meters) in length with timber casement windows and several entrances along both long sides.

From 1940 to 1942, staff led by Alan Turing decrypted naval radio messages encoded by the German Enigma machine. The work concentrated on U-boat communications, whose decipherment proved crucial for the war in the Atlantic.

The name refers to its role as the eighth timber structure on the estate where naval codebreaking teams worked during the war. Today the building still shows the plain working environment where mathematicians and specialists operated under pressure around the clock.

The building is accessible through guided tours at the Bletchley Park museum, where guides explain the working methods of the codebreaking experts. Visitors can enter the interior spaces and view the original wartime fittings that remain in place.

The Big Room inside preserves original wartime features including five doors and radiators that witnessed the daily operation of the codebreaking teams. These details allow visitors to sense the spatial atmosphere of the working environment at the time.
