Much of northern Spain belongs to Castile-Leon, an autonomous region surrounded by mountains. Architectural gems like the Romanesque stonework of Segovia's city walls, the Gothic Burgos Cathedral and the dramatic Baroque square in Salamanca are complemented by the area's natural beauty. Parque Natural de las Hoces del Rio Duraton is marked with deep gorges and shelters many birds of prey, while Parque Natural del Lago de Sanabria y alrededores contains the largest glacier lagoon on the Iberian Peninsula.

Segovia is a picturesque old city with twisting alleyways, the highest concentration of Romanesque churches in all of Europe and pedestrian-only streets, all bordered by a medieval wall and two rivers. In 1985, this sleepy Castillan town was declared a World Heritage site by UNESCO. One of the main tourist attractions is Alcázar, a royal palace built sometime around the 11th century where Queen Isabel agreed to fund Christopher Columbus’ exploration of the New World. The picturesque palace is said to be Walt Disney’s inspiration for Cinderella's Castle.

Known as Spain’s "golden city," Salamanca is rich in architectural, religious and gastronomic culture. Marvel at the La Casa de las Conchas (house of shells) and the 18th century Plaza Mayor, then pore over the fresh produce of the Central Market. Both the Old and New Cathedrals of Salamanca are celebrations of Renaissance and Gothic styles.

Rich in medieval architecture, the northern city of Burgos provides a glimpse into bygone Spain. But the historic capital of Castile looks to the future, too, with its modern museums, celebrated culinary scene, and award-winning infrastructure.
