In the 18th century, José González Laso, Bishop of Plasencia, carried out major building projects in the area, including the restoration of the Spa, which was later continued by Juan de Porras y Atienza, Bishop of Coria. The first building for the spa, whose brick vaults are still preserved, was built in that time.

The 19th century was the time of the greatest popularity of the spa, and a new building was constructed for it as well as a hotel. Baños de Montemayor became a holiday resort and summer residences were built in the architectonic styles of the time.

The hot springs are undoubtedly the elements that have most contributed to the fame of Baños de Montemayor. The sulphated, sodium and oligometallic water flowing from two springs near one another, called Column and Arqueta, has a temperature of 43°C. The water is suitable to treat rheumatological processes, arthrosis and breathing problems, and also to tone and embellish the skin.

The spa is now regarded as one of the most advanced and modern in Europe. It offers a wide range of treatments, both therapeutic and for relaxation and beauty, together with an array of hygiene and beauty products made with the spa water.
