Playa de Las Catedrales translates as 'Beach of the Cathedrals'. It is the touristic name of Praia de Augas Santas (in Galician language : 'Beach of the Holy Waters').
The Spanish beach is located in the Ribadeo municipality, in the province of Lugo (Galicia), on the Cantabric coast and it lies about ten kilometres to the west from the town of Ribadeo. Its name is derived from the formations of its cliffs.
It has been declared a Natural Monument by the regional Ministry for the Environment of the Xunta de Galicia.
