The intervention area is located in a valley area with granite slopes. The approach to the building complex is made by a single access road that winds through the valley until we approach the built-up area on the lowest level. The built ensemble is characterized by the building of the old shelter, located halfway up the slope and parallel to the stone walls that define the various platforms that rise up the hill. This is one of the perpendicular axes that define the set of spas and that intersects with the other axis defined by the set of stairs that connect the thermal spa building — located at the lowest level near the Ribeira de Coja - and the chapel, located in the top of the rise to the west.
