4. The Shared Sea

Where in the Channel does England end and France begins?

Dr Renaud Morieux, senior lecturer in History at Cambridge University, examines how that understanding has influenced peace, conflict and trade.

And in the company of Dr Susan Foister, Deputy Director of the National Gallery, he reflects on what Turner's painting of Calais Pier reveals of the Channel at the time.

The Channel is a reflection on the stretch of water that both separates us from and connects us to Europe.

The series examines how this waterway has affected our British identity through time, and continues to do so.
