Those who arrive there are forced to take a path that proceeds further and further downwards. In doing so, the visitor completely loses sight of the horizon. It is as if for a moment it were somewhere else, neither in a human nor in a natural place. The first contact with nature returns when, at the end of long corridors, the Atlantic sky can be glimpsed, but in any case, the waters remain hidden until the last moment.
A subtle play on the senses, this element seems to slice the landscape in two, leaving only sky visible above and the sea audible beyond. The composition of these elements as building proper is understood only from the perspective of the swimming pools, since from the road they appear as an abstract figure, a series of carvings into the landscape.
Many of the materials of the swimming complex had already been used by Siza at Boa Nova and in other early projects, but here they achieve an unusual level of homogeneity: the rough concrete, of a slightly cooler hue than the rock formations, smooth and washable concrete panels for the pavement, Riga wood carpentry, and green copper roofs, which seen from the coastal avenue attain a color similar to the pools.
