As you go round the Nissen huts at Bletchley Park you may feel as if you are stepping back in time to the war years and might almost expect to hear sirens.

Of course you won’t want to miss Turing and his team’s actual device for decoding the enemy’s Enigma machine. You will be pleased to find that there are excellent audio guides that will explain the intricacies.
A light lunch can be purchased at either of the two cafés, or you can take sandwiches.
