Heritage Open Day: This new exhibition at Southend Central Museum focuses on the last voyage that objects from the wreck of 'The London' warship undertook before reaching the museum: uncovering the process behind their conservation and preservation. Built between 1654 to 1656, the 'London' was a 64-gun warship that served during the Anglo-Spanish war and later transported the Duke of York (future King James VII and II) during the restoration of the monarchy. In 1665, the ship tragically and mysteriously exploded while moored in the Thames Estuary, killing around 300 people, a disaster recorded by Samuel Pepys in his diary.
