Alarcón Castle is a remarkably well-preserved fortress in Cuenca, Spain, with over 13 centuries of architectural evolution spanning pre-Roman, Moorish, and Christian periods. Perched atop Pico de los Hidalgos, the castle commands views of the Júcar River gorge and features three original fortification lines, a central courtyard with an ancient cistern, and a Renaissance-era tower of homage displaying Gothic styling. The stronghold has hosted notable residents including Don Juan Manuel (1282-1348), the medieval author of El Conde Lucanor. Now operating as the Parador de Alarcón luxury hotel, the castle maintains its historical atmosphere with period-appropriate stone ceilings and decoration while offering contemporary amenities and dining.
