Room 40 is a video mapped installation investigating forms of digital surveillance by reconstructing GCHQ the British government intelligence agency through gathered second hand information with a soundtrack by Martin A. Smith.

During the WW1 the code breaking section of the Admiralty was known as Room 40.

GCHQ was originally established after the First World War as the “Government Code and Cypher School” and was known under that name until 1946. During the Second World War it was located at Bletchley Park, where it was famed for its role in the breaking of the German Enigma codes. In 2013, GCHQ received considerable media attention when NSA whistleblower Edward Snowden revealed that the agency was attempting to collect all online and telephone data in the UK via the Tempora programme.

From its humble beginnings GCHQ now covers a site of 176 acres in Cheltenham, UK.

Shown at Watermans as part of their Networked Bodies event and exhibition 7th-9th November 2014.
