Castle in the Round - Queensborough, Kent

The team investigate the remains of Queenborough Castle on the Isle of Sheppey, built by Edward III for Queen Philippa during the Hundred Years' War. The Time Team excavate the castle mound, and opinion is divided whether this unique circular structure was built for defence or as a royal bolthole from the plague. They are joined by archaeologist Oliver Creighton, medieval historian Sam Newton and architectural historian Jonathan Foyle.
