Muralla de Sepúlveda encompasses an extensive fortification system built during the 10th and 11th centuries using Andalusian construction techniques, surrounding the Somosierra hill in Segovia province. The wall's 3,900-metre perimeter enclosed approximately 68 hectares, with just over one kilometre of actual walls complemented by natural cliff defences. The fortress became known as the "Villa of the Seven Gates" due to its multiple historic access points that were closed each night: Puerta de Duruelo, Puerta de la Fuerza, Puerta del Azogue, Puerta del Postiguillo, Puerta del Río, Puerta del Vado, and Puerta de la Judería. Today, fragmentary sections remain, with the best-preserved portions being Trascastillo, Barbacana, and Postiguillo.
