Castillo de Guadalerzas

Spain, Spain

---

The Castillo de Guadalerzas is a medieval ruin located near Los Yébenes in Toledo province, Castilla-La Mancha, Spain, built originally as a Muslim stronghold to guard a strategic mountain pass on the key route south from Toledo.

Conquered by Alfonso VI during the Reconquista, it was transferred to the Order of Calatrava, who constructed a hospital atop it by the late 12th century, reflecting its shift from military outpost to a site supporting pilgrims and locals. 

Perched on a hill amid rural valleys northwest of Urda, the deteriorated fortress now stands as a historical remnant offering views of the surrounding countryside, tied to the military orders like Calatrava and the Templars.
