If there's one place in Asturias that exudes history, it's the Roman Bridge of Cangas de Onís, or, as it's popularly known, El Puentón. Its robust and elegant silhouette rises above the Sella River, connecting the municipalities of Cangas de Onís and Parres , and for centuries it has been a must-see for anyone wishing to immerse themselves in the purest essence of Asturias. Although its name might be misleading, this bridge is not Roman, but medieval , built during the reign of King Alfonso XI of Castile in the 14th century . However, its location is not accidental: it occupies the site of a former Roman bridge, part of the road that connected Lucus Asturum (present-day Lugo de Llanera) with Portus Victoriae (now Santander).
A medieval bridge with a Roman soul
The bridge's current structure, despite its Roman name, is Gothic in style. It consists of three arches of unequal size, the central pointed arch being particularly noteworthy , giving the bridge its majestic and distinctive appearance. Its function has always been strategic: travelers, merchants, and armies have all crossed it , perhaps even the first Christian warriors who, led by Pelayo, ignited the spark of the Reconquista in Covadonga, just a few kilometers away.
Throughout its history, the bridge has undergone several restorations. The most significant took place in 1876, when the municipality of Cangas de Onís carried out extensive repairs, commemorating the work with a plaque. In the 20th century, following the Spanish Civil War, the bridge was restored again between 1940 and 1943 under the direction of architect Luis Menéndez-Pidal y Álvarez , who also worked on the conservation of other Asturian monuments.
The Victoria Cross: a pendant emblem
One of the bridge's most iconic features is the large Cross of Victory that hangs from its central arch . This cross, an undisputed symbol of Asturias, was placed there in 1939, coinciding with the return to Spain of the image of La Santina (Virgin of Covadonga), which had been evacuated to Paris during the Civil War. Since then, the cross has presided over this river crossing as a symbol of Asturian identity.
