In the heart of Oviedo lies a unique monument of medieval engineering — the La Foncalada fountain. This ancient stone structure, built in the 9th century, is considered the oldest piece of civil architecture preserved in Spain. Built over a natural spring, it has supplied the city's residents with clean drinking water for many centuries.

The fountain is a recognized UNESCO World Heritage Site and part of the Pre-Romanesque heritage of the Kingdom of Asturias. Its architectural value lies in the fact that it is the only surviving example of an early medieval urban public structure in this region. La Foncalada is a small building made of hewn stone with a gable roof, decorated with the symbolic Victory Cross.
Today, this historic spring remains functional, continuing to delight visitors with its cool water and remarkable preservation. For tourists, the fountain has become a symbol of Oviedo's rich past, a place where you can literally touch the daily life of people who lived here over a thousand years ago.
