Balneario de Caldeliñas

Balneario de Caldeliñas is the ruined thermal spa standing in the parish of Vilamaior do Val, roughly 2.5 km from central Verín in the province of Ourense, Galicia, along the road toward Laza. Locals still call it simply "El Baño." The buildings have stood empty for decades, but the spring itself keeps flowing, and the site has recently become a small landmark on the region's thermal heritage trail.

How old is the site, really?

The earliest written references to the spring at Caldeliñas date back to the 16th century, and the site turns up again in cadastral records from 1753. The waters are believed to have been used since ancient times, much like several other thermal springs around Verín that were already valued in Roman times. The masonry building whose ruins visitors see today — the former hotel — was raised in the mid-19th century, around 1850.

Who developed the spa, and why did it close?

The spa's real heyday began in 1887, when it was bought and expanded by the French photographer Fernand Debas, who turned it into a fully-fledged bathing establishment with hotel facilities. After Debas died in 1914, the business went into decline, and by 1946 the therapeutic baths had stopped operating altogether. The buildings were left to crumble for decades afterward.

What is left to see today?

Visitors will find the consolidated ruins of the main hotel building alongside a smaller structure that houses the spring itself. Inside that smaller building, small pools still show the thermal water in motion, its surface often coated in the green algae typical of alkaline springs. In recent years, the ruins have been cleared and stabilized, and a public spout was installed at the spring so visitors can access the water directly.

What makes the water at Caldeliñas distinctive?

The spring discharges at 24.4°C with a pH of 6.8, putting it in the medium-mineralization range. Its dissolved minerals are dominated by bicarbonate, lithium, sodium and fluoride. Historically the waters were prescribed for skin conditions, rheumatism, arthritis, gout and neuralgia, though the relatively high fluoride content means drinking it without medical guidance is not advisable.

What is being built at Caldeliñas now?

The former spa grounds now fall under the Special Plan for Infrastructure and Facilities of the Caldeliñas Balneario-Care Complex, approved in 2021. The plan centers on a care residence for 100 dependent elderly residents, named San Rosendo, expected to employ around 50 staff. The project received its building license in August 2025, and construction is underway led by the local firm Construcciones Ropán. The plan also calls for restoring the historic 1850 bathhouse building and, further down the line, building a new hotel-spa next to the residence, complete with a thermal water room for residents. The residence is expected to open in 2028.
