As Catedrais Beach, in Ribadeo, is much more than one of Galicia’s most visited landscapes. Its slate and schist cliffs, shaped by waves and tides, provide a live demonstration of how geology transforms the coastline. Arches, columns, fractures, and landslides turn this protected enclave into a window into our planet’s past and a natural laboratory for understanding coastal processes.
