Castillo de Uclés is a medieval fortress in Cuenca, Castilla–La Mancha, with origins traced to approximately the late 9th or early 10th century when al-Fath ibn Musa ben Zennun constructed it as his primary stronghold. The fortress passed through numerous hands following Christian conquest of Toledo in 1085, and was eventually granted to the Knights Hospitallers in 1163, later transferred to the Order of Santiago in 1174, which established it as their Casa Madre. Today, three towers approximately 30 meters high remain standing, notably the Tower of Hommage and Tower of Plata, connected by partial fortification walls. A monastery begun in 1529 was constructed over nearly two centuries alongside the castle ruins, creating a striking mixture of architectural styles that represents the site's layered historical significance.
