The Tidal Pools of Leça da Palmeira (Portuguese: Piscinas de Maré de Leça da Palmeira) is a swimming area on the beach of Leça da Palmeira, along the coast of the civil parish of Matosinhos e Leça da Palmeira, municipality of Matosinhos, in the Portuguese northern district of Porto. The structures consist of two natural pools filled with fresh sea water, designed and built between 1959 and 1973 by Portuguese architect Álvaro Siza Vieira.[1] Situated 1 kilometre (0.62 mi) from the Boa Nova tearoom and restaurant, it is considered one of Siza Vieira's early projects.
