Aguas Termales Tiermas Aragon

Aguas Termales Tiermas Aragon is associated with Tiermas, a historic village now largely submerged beneath the Yesa Reservoir in Zaragoza Province, Aragon, Spain — a Roman-era thermal settlement whose ancient baths were flooded in 1959 when the Yesa Dam was built, creating one of Spain's most melancholy examples of a thermal heritage lost to the demands of 20th-century water engineering. The chloride-rich thermal waters that once made Tiermas a celebrated Roman bathing site — Aquae Tiernae in Latin — still emerge near the reservoir's edge, where new thermal facilities have been developed to recover and honour this ancient geothermal heritage at the foot of the Pyrenean foothills. The dramatic landscape of the Yesa Reservoir, where the old village emerges ghost-like from the water during periods of drought, provides one of Spain's most haunting and historically evocative settings for thermal bathing in the shadows of a submerged Roman past.
