Termas de São João do Deserto

Termas de São João do Deserto is a thermal complex with mineral springs divided into two separate sections, each with its own pools. The different areas are designed for various therapeutic treatments based on the distinct mineral compositions of each spring.

These thermal springs have been valued for healing purposes from medieval times through the mid-20th century, with evidence suggesting earlier use by Carthaginian and Roman visitors. The long history demonstrates how multiple cultures across the centuries recognized the therapeutic potential of these mineral waters.

The spring served as a gathering place where people from the surrounding region came together seeking relief from skin ailments in the mineral-rich waters. Local shepherds also regularly brought their animals to drink and bathe in these springs.

The site is located at coordinates 37.875767, -8.166617 and retains its original structures despite lacking formal heritage protection status. Visitors should expect to find the site in its historical form without modern amenities or recent renovations.

The two springs were classified at the 1867 Paris Universal Exhibition as strong source and weak source based on their different mineral compositions. This 19th century international recognition reflects the scientific attention these waters received during that era.
