The hypocaust heating system discovered here is one of the best-preserved examples in the Cantabrian region.
The complex was constructed using local materials, primarily sandstone, which is characteristic of Roman building techniques in the area.
Archaeologists identified the remains of a 'praefurnium', the furnace area where slaves would have maintained the fire for the thermal baths.
The bath complex was likely abandoned around the 4th century AD during the decline of the Roman influence in the region.
Excavations at Valduno have provided critical evidence regarding the trade routes and logistics of Roman military and civilian settlements in Asturias.
The Termas romanas de Valduno represent one of the most significant Roman archaeological sites in Asturias, featuring well-preserved remains of a public thermal bath complex. The site contains the structural foundations of the caldarium (hot room), tepidarium (warm room), and frigidarium (cold room). Excavations have revealed a complex hypocaust system, which utilized an underground furnace to circulate hot air beneath the floor. Built during the 1st or 2nd century AD, the baths served a nearby Roman settlement, likely linked to the strategic route between Lucus Asturum and Flavionavia. The site includes a modern interpretation center that displays artifacts recovered during excavations. Visitors can view the layout of the bathing chambers and the sophisticated water distribution systems through elevated walkways. The ruins are situated in the rural landscape of the Las Regueras municipality. It stands as evidence of the Romanization process in northern Iberia.

Wear comfortable, flat-soled walking shoes suitable for gravel and uneven paths around the ruins.
Bring sun protection as the site is largely exposed to the elements with limited natural shade.
Check local regional tourism websites before traveling to confirm if a guided tour is required or available for that day.
Do not expect a large-scale museum; this is a focused, open-air archaeological site that is best appreciated if you have an interest in Roman engineering.
The site is typically closed on Mondays and Tuesdays; always verify current access status via the local Las Regueras municipal website before arrival.
Do not climb on the stone ruins or step over the barriers separating visitors from the archaeological remains.
