The Natural Arch is a rock formation of the Paleolithic age 12 meters wide and almost 20 high which, due to the atmospheric agents and geological processes that have affected the island in the past, has acquired a curious arch shape. The view that can be enjoyed from the small square in front is that of the Sorrento Peninsula, in particular of Punta Campanella, and of the islets that make up the Li Galli archipelago.
