Beach of the Cathedrals ( Praia de Augas Santas). This beach is located in the Ribadeo municipality, in the Spanish province of Lugo (Galicia), on the Cantabric coast, and it lies about ten kilometres to the west of the town of Ribadeo. The characteristic features of the beach are its natural arches and caves, which can be seen only at low tide. During high tide, the beach appears small. During low tide the size of its cliffs and sea caves is more apparent, ranging from small cracks on the rock to big caves whose roofs have collapsed due to the erosion of the waves. Oil, canvas.
