I think this is flat out fascinating.

Cryptography experts from UK’s historic decryption center Bletchely Park intercepted and decoded many of the messages that were encrypted by Germany’s Enigma machine. These are messages include transmissions about how the Germans thought the Americans were going to land somewhere other than Normandy in June 1944. While the Bletchely Park estate has fallen into disrepair, the messages it intercepted and decoded are all crusty old paper stored in boxes. Now they’re being digitized.
