The heart of Spain too often ignored by international tourism, Castile is a melting pot of history and art.
From modern Madrid with its superb museums and its life, to the Arab Toledo projected from the Middle Ages, Salamanca home to an ancient and prestigious university and full of churches and palaces, Valladolid which was the capital before the unification with Aragon, passing through an infinite number of lesser-known cities (Aranjuez, Cuenca,....), you can wander around for weeks without ever getting bored.
