Castell de Cervera del Maestrat is a fortified Islamic fortress crowning a historically significant hill in Cervera del Maestre, Baix Maestrat, Valencian Community. Constructed during the twelfth century as an Almohad border castle, the fortress was strategically positioned to halt Christian advancement during the Reconquista, forming part of a defensive line alongside the castles of Peñíscola, Xivert, and Morella. Archaeological evidence reveals continuous occupation from the Iron Age and Iberian periods, with an Islamic Hisn Califal settlement predating the fortress. After Christian conquest, the Orders of San Juan del Hospital (1233) and Santa María de Montesa (1319) took possession, making it the political-administrative center of the Old Maestrazgo de Montesa region throughout the fourteenth, fifteenth, and sixteenth centuries. Occupying approximately 7,500 square meters at the town's summit and designated Cultural Heritage in 2003, the castle's illuminated perimeter remains a prominent landmark symbolizing centuries of frontier conflict and cultural layering in eastern Spain.
