Open Cambridge bigger and better than ever

The ancient and sometimes mysterious doors of Cambridge University will open to the public this September, giving thousands the chance to glimpse into hidden corners of both the University and city as a whole. From the prison letters of acid bath murderer John George Haigh to the latest laser technology at the £15m Institute for Manufacturing (pictured), the Open Cambridge weekend of September 10-12 will shine a light on the weird, wonderful and sometimes unexpected treasures to be found behind doors often closed to the public. For one weekend only, visitors from Cambridge and the rest of the UK will be granted access to a whole host of University and city-wide venues that cover some of the most diverse and eclectic collections in the country. The booking website for the free tours, talks and open access events opens today at www.cam.ac.uk/opencambridge. Open Cambridge organiser Sue Long said: "Both the University of Cambridge and the city are treasure troves full of some of the most amazing and unusual items. We have everything from AA Milne's manuscript of Winnie the Pooh to tours of a Mechanical Biological Treatment Plant on offer. "And this year we are delighted to be able to offer tours and activities specifically designed for children and families.
