Castilla y León
The Heartland of Kingdoms, Cathedral of Stone
Castilla y León is the largest region in Spain and the birthplace of the Castilian language—which became Spanish. Its golden-stone cities—Salamanca, Segovia, Ávila, Burgos, León—are living museums of Romanesque, Gothic, and Renaissance architecture. This is where El Cid rode, where Isabella was crowned, and where the foundations of an empire were laid.
