Coast ventures out to brand new territory, the astonishing man-made shoreline of the Netherlands. Nick Crane explores how ingenious Dutch engineers created massive coastal defences like no others on earth following the great North Sea flood in 1953 which killed thousands of people in the Netherlands and Britain. Nick also discovers how, during the Second World War, traitors from the British Indian Army took part in the Nazi occupation of the tiny isle of Texel - the unlikely site for the last battle in Europe of the Second World War. Coast newcomer, historian Tessa Dunlop, is on the trail of Tulipmania, the extraordinary trade in tulip bulbs that's said to have nearly bankrupted the Dutch nation nearly 400 years ago. Mark Horton reveals the age old skills that have made the Dutch the Grand Masters at creating new living space from the sea. Adam Henson, himself a farmer, investigates why cows from the coastal plains of the northern Netherlands became the most sought after milk producers in the world, and one of the most familiar sights in the British countryside. Miranda Krestovnikoff experiences how the Dutch delight in devouring raw herring as a sea side snack!
