• Monumental natural cavity developed on the cliff, also known as "Cathedral" (Cova do Sono means hole of the sleep).

    This geophorm has an arcuate structure with roof-shaped dome, whose base is a small pebble beach. Its genesis is associated with erosion at the base of the cliffs caused by the continuous action of the waves; the erosion decreases in intensity from the bottom to the top, where essentially it is due to the action of weathering waters.
