The site was historically associated with the Moorish leader Al-Azraq during the 13th-century conflict against James I of Aragon.
Excavations have uncovered Almohad-style ceramics, confirming the site's peak usage between the 11th and 13th centuries.
The castle served as a key signal tower, using fire and smoke to communicate with other fortifications in the Sierra Calderona network.
Due to its high altitude, the ruins offer a clear line of sight to the Mediterranean Sea on cloudless days.
The fortification layout follows the natural crags of the mountain, making the terrain itself a primary component of its defensive architecture.
Castillo del Real is a fortified defensive site located in the Sierra Calderona mountain range near Olocau, Valencia. The ruins occupy a strategic hilltop position at an elevation of approximately 500 meters, overlooking the Camp de Túria valley. Archaeological evidence identifies the site as an 11th-century Islamic fortification, known as 'Al-Qal'a'. It served as a critical defensive outpost for the Moorish control of the region before the Christian reconquest. The remaining structures include segments of stone curtain walls and the foundations of several defensive towers. The site is accessible via an unpaved hiking trail that leads directly to the mountain summit.

Wear sturdy hiking boots as the path is rocky and includes loose gravel.
Bring at least two liters of water, as there are no services or shade available on the trail or at the summit.
Visit during the spring or autumn, as the summer heat in the Sierra Calderona is intense and lacks cover.
Attempting the ascent during mid-summer afternoons or in high wind conditions, as the path is exposed with no natural shelter.
