Once one of the world’s best kept secrets, Bletchley Park near Milton Keynes is now one of the most significant heritage sites of the 20th century, so far attracting some 190,000 visitors keen to see where the Enigma code and other enemy signals were cracked, shortening World War II and saving countless lives. It all began in 1992 when the Bletchley Park Trust was set up to preserve and refurbish the buildings where the codebreakers had worked but which had fallen into such a bad state, they were almost beyond saving. With a grant from the Heritage Lottery Fund and other sources, funding was secured in 2011 for the £8 million restoration project.
