The little Romanesque chapel of A Lanzada stands alone on a rocky promontory at the north end of the long beach, dating from the 12th century. It is built from the same granite as everything else in Galicia, weathered to a soft grey by the salt and wind. Inside, the apse retains carved corbels and a small Marian altar. Mass is still said there on a few key dates each year.
The setting is the real draw: the chapel sits between the open Atlantic and the dunes, with views back along the beach to the south and out to the Ons Islands to the west. At sunset it is one of the loveliest spots on the Galician coast. The footpath up to the chapel from the beach is short and stepped, and the view from the headland justifies the climb.
