Castell de Corbera, Medieval fortress on hilltop in Corbera, Spain.

Castell de Corbera is a medieval fortress built on a hilltop in Corbera, constructed with limestone and mortar. The structure features irregular walls that formed part of a defensive system and show different phases of fortification.

The fortress was built in the 11th century on Roman foundations and controlled the foothills of the Sierra de la Murta. It was destroyed during the Germania revolt in 1521, marking its military end.

The castle walls bear Kufic inscriptions praising Allah, showing the Islamic architecture that influenced its construction. These carved texts remain visible today and tell of the religious and cultural meaning the site once held.

The castle stands on a promontory above Corbera, reached by a path that climbs the hill; the terrain is steep and rocky, so sturdy shoes are needed. The site is owned by the Diputació de València, and consolidation work on the walls has been under way since 2018, so some areas may be fenced off.

The 16-metre albarrana tower stands apart from the main wall line, and the entrance still passes through a barrel-vaulted arch. The site was owned by the Diputació de València, which funded the first excavations in 2017 under Miquel Gómez Sahuquillo; these uncovered Late Roman, Islamic, medieval and Renaissance ceramics plus prehistoric Bronze Age sherds.
