The Museum at Colchester Castle will be closed after 6 January 2013 for major redevelopment and will open once again in Easter 2014.
The Colchester Castle Museum website says:
The site will be open to the public for a short while after the museum artefacts are removed so that the bare interior can be viewed. The Essex Society for Archaeology and History is planning a Visit in April 2012 for its members.
The Museum is of importance to the Essex Society for Archaeology and History because in its early years its members gave a large number of antiquities to form the main part of the collection. In 1927 W Gurney Benham mentioned in his Guide to Colchester that "The Colchester Museum is chiefly the property of the Colchester Town Council, but partly also the Essex Archaeological Society, whose library is also housed here".
