The royal palace
When King James I of Aragon conquered Xàtiva in the 13th century, the Montsant became the town’s royal palace, both for James himself and for his successors Peter II, Alphonse II and James II. It also served for several years as the palatine residence of the exiled Princess Eudoxia Laskarina of Byzantium. The large Aljibe reservoir, which was built during this first Christian period, still survives.
