The living history camp will be open from 10am-4pm and is free. Stuart Orme, Cromwell Museum curator, said: "We're working very hard on the museum's refurbishment at present, which will highlight our remarkable collections as well as create a space that is more welcoming to visitors. "This event in association with our friends in the Sealed Knot will help celebrate our refurbishment and help raise some additional funds towards the works." The museum is expected to reopen by the beginning of March and in the meantime a temporary exhibition from its collection will be at the Town Hall from the end of October. A new display will be created during the upgrade, highlighting its internationally-important collections and telling the story of Oliver Cromwell in a more engaging way. The Levellers were a radical movement which grew out of the English Civil War and called for regular parliaments, universal male suffrage, religious tolerance and equality before the law. Many of the Levellers were part of Parliament's New Model Army and in May 1649 staged a mutiny to try to get their demands heard. They were surprised by Cromwell at Burford in Oxfordshire and the story of what happened will be told during the re-enactments with the aid of Colonel John Pickering's Regiment of the Sealed Knot.
