Founded in 1151, the monastery was the royal pantheon of the Crown of Aragon from the end of the 14th century to the 15th century, when it reached its maximum splendor. The monastic complex consists of 3 well-differentiated enclosures intercommunicated by doorways. The central enclosure constitutes the monastery itself.
