Castillo de Autol is a rock castle perched on an inaccessible crag in La Rioja, Spain, featuring probable Muslim origins dating to the 10th-11th centuries. The fortification holds significant historical records from 1036 onward, with notable medieval ownership including donations by kings of Navarra and Castile. Archaeological discoveries reveal Celtiberian ceramics extending the site's documented history to at least the 6th century BC. Though progressively ruined, sections of the keep and walls remain standing. This Cultural Interest Asset commands striking views over the surrounding landscape and represents an important medieval military stronghold that survived numerous conflicts, including a dramatic 30-day siege in 1445 when the local population reclaimed it from robbers.
