- A visit to Colchester Castle Museum takes you through 2000 years of some of the most important events in British history. Once capital of Roman Britain, Colchester has experienced devastation by Boudica (Boadicea), invasion by the Normans and siege during the English Civil War. Since the 16th century, the Castle has been a ruin, a library and a gaol for witches. Today it is an award winning museum featuring many hands-on displays showing Colchester's history from the Stone Age to the Civil War. This museum has a Designated Collection of national importance.
