Valladolid breathes history. This is the place where King Felipe II was born, the Catholic Monarchs Ferdinand and Isabel were married, and Christopher Columbus died. This was once the capital of Spain, and although it has lost this title, it's still the principal city of Castilla y Leon, the land of castles from which the word ‘Castilian’ is derived. Today, Valladolid is a bustling university city that thrives on its manufacturing industries. It is a down-to-earth, lively place that blends the old with the energetic new.
