CYSIAM's operational HQ is located in the historic Bletchley Park Mansion House, once the top secret home of World War II code breakers.  Bletchley Park is the birthplace of the first programmable computer, the intelligence hub that gave us meta-data analysis, and the team that helped shorten the second world war, saving countless lives.
