Sancho Garcés III de Pamplona
In mountainous regions, castles often take highly irregular forms, adapting the plan to the site in varied ways. Castles have often developed over the centuries and typically have had additional encircling walls added. Between 1072 and 1080, Sancho III of Navarre (the Great) built Loarre Castle on a high rocky ridge in the foothills of the Pyrenees, as a commitment to the Reconquista. The castle was further fortified in the 13th century by an outer wall with ten towers. Although outwardly of austere appearance, Castle Loarre has living quarters of comparative comfort, and a chapel ornamented with fine carvings.
