The first work of Álvaro Siza Vieira was inaugurated in 1966 and classified as a National Monument 40 years later. It is considered an example of harmonization between the built space and natural conditions, sheltering among the rocks and becoming fond of them. It is open to the public during the bathing season and can be visited at any time of the year by appointment through the Casa de la Arquitetura: tours@casadaarquitectura.pt
