Unhais da Serra water – Thermal spring water with a history

It is likely that Unhais da Serra water was already famous among the Romans (Leitão, 1993). More recent references date back to the first settlers. A Medicinal Waters Manual from 1726 (Fonseca Henrique, 1726) describes Caldas da Covilham as ‘a sulphur spring in Unhães da Serra, a village in the Covilham municipality, in the Guarda district, whose water fills a tank large enough for 5 baths…’
In the 18th century, the region already boasted a thermal spa, known as a “hot bath”, which consisted of a single sand-bottomed tank where 6 people suffering from different ailments could bathe (Guerreiro et al., 1982). The tank was probably located over the spring, currently known as “Bath Spring” and recently neutralised.
Fully renovated, the thermal spa is now part of the H2otel/Aquadome complex, in Unhais da Serra.
