Heritage Open Day: A much loved museum in the picturesque Castle Park, this is the annual opportunity to explore this fascinating building free of charge. Colchester Castle is Europe's largest Norman keep and was built on the foundations of the Roman Temple of Claudius. It was constructed around 1076 by William the Conqueror and has been a royal fortress, prison and, since 1860, a museum with internationally important Iron Age and Roman finds from the local area.
This Summer's special exhibition is 'Mythical Creatures' which explores how people in the past perceived the world around them.
