Castillo Ben Yucef - Centro Interpretación Orden de Santiago

Terrinches, Spain, Spain

---

Castillo Ben Yucef in Terrinches, Ciudad Real province, Spain, is a 13th-century fortress possibly adapted from an earlier Almohad tower following the Christian victory at Las Navas de Tolosa in 1212, forming part of the Order of Santiago's defensive network in the Campo de Montiel.

The square stronghold, measuring 17 meters per side with 4-meter-thick masonry walls and circular corner towers, famously withstood a 1282 siege by Sultan Aben Yucef of Morocco, where the alcaide's resolute wife rallied defenders against fire attacks.

Now restored as the Centro de Interpretación de la Orden de Santiago, it showcases the order's military repopulation efforts and houses exhibits on medieval frontier life amid its well-preserved ruins.
