The Walls of Albarracín form one of Spain's most complete medieval fortification systems, stretching over a kilometer along the ridge above this historic Aragonese town. Originally constructed between the 10th and 13th centuries when Albarracín served as capital of an independent Taifa under the Berber Banu Razin dynasty, the defensive system bears traces of three distinct construction periods. Key components include the Torre del Andador, the town's oldest 10th-century fortification at its highest point, and the Torre de Doña Blanca, a 13th-century watchtower that worked in concert with other towers to relay warning signals. The river gorge below provided natural defensive advantages, while a restored walkway today permits visitors to trace the medieval ramparts and experience this remarkably preserved example of medieval military architecture.
