Castilla y Leon, formed by the merger of two separate regions in 1983, holds the distinction of being the largest region in Spain. Steeped in history, this region is a treasure trove of architectural wonders, with Roman structures, Gothic cathedrals, and more medieval castles than anywhere else in Europe.
Everywhere you look in Castilla y Leon, the region’s rich cultural heritage is on full display. But perhaps nowhere is this more evident than in the magnificent Roman aqueduct that runs through the city of Segovia. A true marvel of engineering, this aqueduct stands as a testament to the ingenuity of ancient civilizations. Carved from vast stones over 2,000 years ago, the aqueduct still supplied the city with water until recent years, and remains one of the best-preserved examples of Roman architecture in the world.
But Castilla y Leon is more than just a region of architectural marvels. From the rolling plains and rugged mountains to the tranquil rivers and lush forests, this region offers a breathtakingly beautiful landscape that is as diverse as it is awe-inspiring.
Whether you’re interested in immersing yourself in the rich cultural history of the region or exploring its stunning natural beauty, Castilla y Leon is a destination that is sure to leave a lasting impression.

The area is surrounded by mountains. In the north is the Cordillera Cantabria and to the south the Sistema Central range and at the north east lies the Sistema Iberico range. This creates a loop of mountains opening towards Portugal. This is on top of the fact that it is situated on the vast high plateau which forms the centre of the Iberian peninsular.

The most important river of the area is the Duero which begins in Soria and crosses westward to Portugal and empties into the the Atlantic ocean.
The region’s exceptional diversity of mountains, plains and rivers produce a range of microclimates and ecosystems rich in flora and fauna including large mammals such as the Wolf and Brown Bear.
