This week a reconstructed WW2 codebreaking machine will try to find the key of the day and break Enigma messages.Read the full story ›
It is story that has inspired books and films - and today one of only a handful of working Enigma machines has been in Cambridge.
The machines, which generated complex codes for the Germans in the Second World War, were supposed to be unbreakable.
That was until the experts at Bletchley Park cracked the code.
Matthew Hudson had the chance to get up close to a real piece of modern history.
A new exhibition examines how Bletchley codebreakers coped with the stress of the job, through government supported recreation time.Read the full story ›

Bletchley Park has had its busiest ever year.
Visitor numbers at the former codebreaking site have shot up from 196,000 in 2014 to more than 280,000 this year. The success is being put down to The Imitation Game film and a host of new exhibitions.
A new exhibition about the work of World War Two codebreaker Gordon Welchman has opened at Bletchley Park.
The former Cambridge University mathematician worked alongside Alan Turing on the design for a machine to break the Enigma code.
He is also known for setting up the famous 'Hut 6 ' at Bletchley where one million German codes were decrypted.
The family of Bletchley Park codebreaker Alan Turing visited Downing Street today to demand pardons for 49 thousand men who were persecuted for being gay.
Turing killed himself just two years after being convicted for homosexuality. He received a royal pardon in 2013.
A petition has been signed by half a million people including Benedict Cumberbatch who played the mathematician in the Imitation Game.

The family of Bletchley Park codebreaker Alan Turing - who was played on the big screen by Benedict Cumberbatch in The Imitation Game - have been at Downing Street today to demand the Government pardons 49,000 other men persecuted for their homosexuality.
Turing, whose work cracking the German military codes was vital to the British war effort against Nazi Germany, was convicted in 1952 for gross indecency with a 19-year-old man. He was chemically castrated, and two years later died from cyanide poisoning in an apparent suicide.
He was given a posthumous royal pardon in 2013 and campaigners want the Government to pardon all the men convicted under the same outdated law.
Turing's great-nephew, Nevil Hunt, his great-niece, Rachel Barnes, and her son, Thomas, have handed over the petition, which was signed by almost half-a-million people.
Two of the region's scientific breakthroughs are being celebrated on a new set of Royal Mail stamps.
Cambridge scientist Frederick Sangers pioneering technique of DNA sequencing is on the £1.47 stamp.
The code breaking Colossus computer, which was built at Bletchley Park near Milton Keynes, is getting a 1st class stamp.
The stamps form part of the Inventive Britain Special Stamps, issued on 19 February 2015.
