Built in 1739 as part of a coastal defensive system against Barbary pirates, it was largely destroyed during the Peninsular War in the early 19th century. Today just a few walls, a portion of the tower, and a well-preserved cistern remain, but it is worth visiting for the great views.

Cala Granadella / Granadella Beach
Granadella Cove and the attached beach of Granadella are one of those hidden little pieces of paradise. The cove is attached to Xàbia but hidden away behind the buzz of the main Arenal beach, and is a spot well worth visiting for its natural beauty, tranquil atmosphere and historic castle ruins. The cove is enclosed by mountains, features a Blue Flag beach, excellent diving facilities and plenty of pure natural beauty. Facilities include toilets and lifeguard station, and jet-skis and canoes are available for rent.
Cabo de la Nao
Another steep, rocky headland, with a lighthouse. During clear conditions it is possible to see as far as Ibiza, 85 km distant. At the base is a large cave (Valencian: Cova dels Orgues / Spanish: Cueva de los Órganos) accessible by sea only.
Cabo Negro
A rocky headland covered with pine trees.
The crucifix is across the bay from the tiny Illa de Portitxol ('Portitxol Island'), and tops steep cliffs. At the base numerous Roman amphoras and other archaeological artifacts from the 3rd and 4th centuries CE have been discovered. This area is a favourite diving spot.
