These salt-water pools were built in 1966 in Leça da Palmeira, Matosinhos, Portugal. At only 26, this project became Siza’s most recognized piece. The entire project consist of two pools, changing rooms and a restaurant and sits within the natural rocks along the coast, leaving the view of the beach completely uninhibited. What makes this site unique is the use of the natural landscape within the project. While the materials are starkly different, the contrast compliments the aesthetic and atmosphere of this piece of art.
