Facing the Bay of Biscay, its backdrop a natural setting that combines sea and mountain, Santander rolls out along a huge bay on the northern coast of the peninsula. A city of maritime tradition, it has a century-old touristic vocation. It is home to two treasures that are UNESCO World Heritage Sites: a part of the Way of Saint James and the Cave of Altamira. Its Prehistory and Archaeology Museum houses one of the most valuable Palaeolithic collections in Europe and the Maritime Museum of Cantabria is one of the most comprehensive museums in Spain dedicated to the sea. Its beaches with peaceful waters, protected from the wind, offer one of the most beautiful sea fronts with a succession of Belle Époque buildings.
