Thermal Spa of Peso
The land was purchased on 8 June 1884 from António Júlio Esteves and his wife by António Augusto de Sousa e Castro, and was immediately registered in the municipal authority on 14 August in order to take advantage of the medicinal waters of Peso (by Félix Tomás de Barros Araújo, Bento Maria Barbosa, António Augusto de Sousa e Castro and Victorino Augusto dos Santos Lima). In their petition, they alluded to the "gaseous alkaline medicinal waters" similar to the public baths in the area referred to as Caldas, in the parish of Prado. Following a series of revisions, on 13 October, a society was constituted to explore the thermal waters, formed by Bento Maria Barbosa, Félix Tomás de Barros de Araújo, António Augusto de Sousa e Castro, Victorino Augusto dos Santos Lima, Abílio Augusto de Sousa, José Francisco de Almeida Fragoso, Aurélia Saavedra e Silva, Dr. António Joaquim Durães, Manuel Bento da Rocha Júnior and Dr. António Pereira de Sousa.
