Bletchley Park 18-7-25 101 Hut 6 Decoding Room

Decoding Room

Once the day’s Enigmas settings, or keys, had been broken in the Machine Room, intercepted messages were typed into Typex machines adjusted to these settings. The deciphered messages, usually in German, then emerged from the machine. The noise from the Typex machines when the ciphers were being decoded could be heard throughout the hut.
