The pool was constructed in the 1970s to provide a safe swimming environment in an area known for high-energy Atlantic surf.
Water renewal depends entirely on the tidal cycle, meaning the water quality and level fluctuate with the sea.
The site is located within a traditional Asturian fishing village known for its historic port and surf culture.
The pool design incorporates stairs and railings to facilitate entry and exit from the rocky basin.
The Piscina de Agua Salada in Tapia de Casariego is a natural seawater pool carved directly into the rocky coastline of the Cantabrian Sea. It functions as a tidal swimming area that refreshes its water naturally with every incoming tide. The structure is reinforced with concrete walls to maintain depth and safety for swimmers regardless of the current sea state. The pool is positioned along the town’s waterfront, separated from the open ocean by artificial stone barriers. It serves as a sheltered alternative to the nearby open-beach surfing waves. The surrounding concrete promenade provides sunbathing space and direct access to the water's edge. Because the water source is the Atlantic, temperatures remain cool throughout the year.

The pool is open seasonally for public use, typically during summer months; water renewal is dictated by natural tidal cycles.
Standard swimwear required; jumping from the perimeter walls is discouraged for safety.
