The Cloister is a courtyard enclosed by porticoed galleries around which the rooms of the Monastery are distributed. Initially the entrance was located in the western gallery, which explains why the porter’s lodge and the hostel are attached to it, followed by the pantry and the cellar. In the 13th century, the Abbot’s rooms were on the upper level.
The northern gallery leads to the kitchen, the refectory and the calefactory, the only place with a fireplace to warm oneself on cold days. From the 16th century it became less important as the monks with specific posts had their own house. In the 18th century, the old kitchen and part of the refectory became the new chapter house. The mongets or young monks, minors educated in the Monastery, were taught in this gallery, the warmest place in the Cloister. Their dormitory was above the aforementioned rooms.
The eastern gallery was originally occupied on the ground floor by the infirmary, which later became the dormitory of the manats or servants and, in the 16th century, the Chapel of the Holy Cross. There is also a stairway to the upper level, the early chapter house, where the communal dormitories and latrines were located.
The southern wing is occupied by the church, which the monks entered through a Romanesque entrance. Its gallery was dedicated to tasks of reading and writing. It is the coolest place in summer but the coldest in winter, so if it was very cold, the monks could move and carry out their tasks in the chapter house.
