Culla Castle (ruins)

Culla Castle stands as a dramatic ruin atop a 1,121-meter peak in Castellón, Spain, representing one of the last and most expensive Templar acquisitions in the Crown of Aragon before the order's dissolution. This 12th-century fortress features the well-preserved Frare Pere tower, 13th-century walls and turrets, and the remarkable barbican entrance gate with coats of arms of the Montesa Order. Built with an irregular floor plan adapted to the mountain's steep topography, the castle served crucial strategic importance during Aragonese territorial expansion. Its dramatic abandonment and later use as a quarry by townspeople during the Carlist Wars has left an evocative silhouette that attracts visitors interested in medieval military history.
