A Living History demonstration on the Market Square will include Roman cookery, a crime and punishment stall and other activities. Visitors will also have the chance to discover lace making, meet Sir Isaac Newton and sit in the town stocks. The free event runs from 10am till 4pm. Later in the day, there will be a talk entitled grim tales and dark deeds in Cambridgeshire at the museum.
