Bletchley Park is now internationally famous as the home of the code-breakers during World War Two. But the endeavours of Alan Turing, Dilly Knox and their colleagues were so top secret that we are only now beginning to learn how they really lived day-to-day in this magnificent house, where – behind closed doors, under the cover of darkness, and against the clock - they determined the course of our wartime history. The house is also fascinating for what it tells us about how the 10,000 men and women working there would live on a daily basis. Artifacts from a Recreation Club – offering activities such as fencing, debating societies and amateur dramatics, amongst others – and film showings suggest an atmosphere not dissimilar to an Oxbridge college, and show a more human side to the story of how they developed the Enigma Machine. In this World War Two Season Special, join Dan Snow on an exclusive tour of the house and grounds, as well as the little known but all-important cottages that surround them. Learn about the men and women whose skill and ingenuity saved millions of lives, and about the machine they developed to help them do it.
