It is certainly the most representative monastery of the Cistercian Route and a historical and architectural treasure. A community of more than 30 monks still lives in it, which gives it authenticity when one tries to envisage the particularities of the monastic life. In 1992, it was declared a World Heritage Site.The building that can be seen today dates back to the 14th century, although the monastery was founded in the 12th century (1129) by order of Ramon Berenguer IV,Count of Barcelona. Its facilities hosted the mausoleums of the Catalan kings Alfons el Cast, Jaime I, Pere el Cerimoniós or Martí l’Humà.The heart of the spiritual life of the monastery is the church, called Santa Maria. It consists of a basilic floor plan that has three naves with a transept, an apse with ambulatory for the passage of pilgrims, a spectacular, pointed or ogival arch and a set of accompanying chapels with a radial structure. Built along the same style lines, the refectory is a room where the monks gather during meals.
