    Visited G block back in february, one of my first proper explores,

    Constructed in October 1943 as an addition to D and F blocks, block G formed part of the Government Code & Cipher School. It comprises of two self-contained but interconnecting elements; a single storey complex of five spurs to the west and a two storey complex of five spurs, arranged in a U-shape formation to the east.

    The single storey spurs to the west housed the ISK and ISOS sections, who dealt with decoding of Enigma and conventional cipher messages from the German secret service. The two storey U-shaped block to the east housed SIXTA, the Army traffic analysis sections, who dealt with the direction of radio intercept stations and analysis of enemy radio traffic.

    After the departure of the Government Code & Cipher School in 1946 the building was used as a training school for the Post Office and then British Telecom. A prefab extension was added during the 60s and 4 training sheds by 1976. Since e closure of the school in 1984 the building has been empty and became part of the Bletchley Park Trust in 1994.
