These ruins are the remains of a late 16th-century watchtower built in defense against Barbary pirates. The site is the location of the former 12th-century Castell de Calp, demolished centuries ago. Although there is very little remaining besides the tower base, foundations, and some rock-cut cisterns, hikers are rewarded with an excellent view of the Penyal d'Ifac and the surrounding area.

Museo de Historia y Arqueología / History and Archaeology Museum
This former residence now displays a range of artifacts from the region, which date from the Bronze Age to the medieval period.
La Iglesia Antigua / The Old Church
The only Gothic-Mudéjar church remaining in the Valencian Autonomous Region, this was built in the 15th century into the side of the old city walls, and is now directly attached to the very modern parish church from the 20th century. Especially noteworthy inside is a 15th-century altarpiece depicting San Antonio Abad, San Cosme, and San Damian.
Museo de Coleccionismo / Museum of Collections
This is a venue for temporary exhibits, located in the walls of a former fortress.
Torreón de la Peca / Tower of Peca
The only remaining portion of the medieval fortress once located here, this includes a preserved tower, section of two walls, and a gate.
Baños de la Reina / Queen's Baths
The ruined structures here were used in Roman times for farming fish, salt production, and salting fish. Finds from the archaeological site can be viewed at the Museu de Història i Arqueologia (listed above). Today parts of the area are fenced off to prevent vandalism, but it is still possible to appreciate the ruins from behind a fence.
