The burial mound's original construction predates the Christian chapel by several millennia.
The chapel holds the distinction of being the first church built in the Kingdom of Asturias after the beginning of the Reconquista.
Archaeological excavations revealed the megalithic chamber was used for funerary rites long before the site was sanctified.
The building was reconstructed in the 1950s to replicate the Romanesque style of its predecessor.
Local tradition claims the Cross of Oak, once housed here, was carried by King Pelagius during his pivotal victory against the Moors.
The Holy Cross Chapel (Capilla de la Santa Cruz) in Cangas de Onís is built directly atop a prehistoric dolmen dating back to approximately 3000 BC. This site served as a necropolis during the megalithic period before being repurposed as a Christian place of worship. King Favila commissioned the original chapel in 737 AD to house the Cross of Oak, which was allegedly used by his father, Pelagius, at the Battle of Covadonga. The current structure is a 20th-century reconstruction following the demolition of the previous building during the Spanish Civil War. The dolmen is accessible beneath the altar, allowing visitors to see the ancient stone burial chamber integrated into the church foundation. It stands as a unique synthesis of Neolithic funerary architecture and medieval Asturian royal history.

Use the provided information panels inside the chapel to understand the transition from megalithic site to royal church.
Examine the floor level carefully, as the dolmen chamber is positioned slightly below the main sanctuary floor.
Combine this visit with a trip to the nearby Roman Bridge, as both represent the dual identity of Cangas de Onís.
Do not attempt to touch the internal stone structure of the dolmen, as it is fragile and archaeologically protected.
The chapel may close for private religious services or mid-day breaks depending on local parish requirements.
Maintain a respectful silence as it remains a place of worship; modest attire covering shoulders and knees is recommended.
