David Dimbleby sails along the coast of East Anglia, exploring how Britain's view of the sea has changed over the past 200 years. The coast and the beach became a playground for the nation, inspiring artists, transforming coastal architecture and creating a seaside culture that remains uniquely British. Setting out from Gorleston-on-Sea, he travels down the Suffolk and Essex coasts and into the Thames, until he reaches Greenwich. Along the way he discovers works of art that reflect Britain's evolving relationship with the sea, meets a sand sculptor and visits the Queen's House in Greenwich, built in 1616 as a waterside retreat for Queen Anne and now home to Britain's greatest collection of maritime artefacts
