King Arthur did not find it but a team of Experts from Bletchley Park (Near Milton Keynes) are trying to crack a 250 year old code that points the way to the legendary cup! The code itself is etched on a Staffordshire garden ornament believed to have connections with the Knights Templars.
Bletchley Park was the secret decoding station during World War II and some say that if it was not for the skills of cryptographers we may not even have won the war! Bletchley is still the location of the National Codes Centre.
