Ruins of the Ganhoteira Thermal Baths.
Between the towns of Aguiar, in the municipality of Viana do Alentejo, and São Bartolomeu do Outeiro, in the municipality of Portel, are the ruins of the Ganhoteira Thermal Baths, which used to belong to the municipality of Évora.
Construction records date back to 1853.
They have been abandoned for about sixty years and currently belong to the Eugénio de Almeida Foundation, which has fenced off the area, but allows access on the rural roads that serve the area. In the past, local residents would come to bathe in these thermal baths, as the water is very ferruginous and hyposaline, forming a red cream on the surface. It was used to treat skin and psychiatric diseases.
The Associação dos Amigos de Alcáçovas, through the Grupo Pedestrianista Alcáçovas Outdoor, regularly organizes hikes in this area of the Serra de Portel.
