Children will be able to take part in a mock trial at Condemned, a new museum devoted to crime and punishment which opens in the 19th-century courthouse of Nottingham's Shire Hall on April 7. They will assume the identity of Victorian criminals and be taken to the cramped cells of the former county gaol next door. The exhibition, the first phase of the Galleries of Justice law museum, covers key stages 2 and 3 of the national curriculum. Entrance: Pounds 2.25 each for school groups of 12 or more. Tel: 0115 952 0555.
