Castell d'Alcalà de Xivert stands at 389 meters on the Sierra de Irta in Castellón province, Valencian Community, showcasing eight centuries of layered history. Built by Moors in the 10th-11th centuries and later seized by the Knights Templar during the Christian Conquest, the fortress blends Moorish and Gothic styles across two distinct zones: the Arab external walled enclosure and Christian interior structures. Expanding over 8,000 square meters with the fortified alcazaba occupying the highest point, this Site of Cultural Interest reveals medieval treasures through ongoing archaeological excavations overlooking Mediterranean vistas.
