The calefactory still has its original windows and ogival door opening to the outside. It was the only heated room in the convent. You can still see the traces of the fireplace's shaft to the right of the door to the chapter house. The Dominicans used it as a kitchen. Today it is the hotel's lounge bar.

The chapter house is, according to tradition, the most finely worked room. It is remarkable for the balance of its three bays, which gracefully rise upward and its wide windows, which originally had been adorned by three rows of small columns. It was in this room that the Assembly of Monks met to deliberate upon affairs of the convent.

Today it is the restaurant.

The cloister  comprises 32 bays, lined up against the morth aisle of the basilica. The three wings of the convent used by the hotel were built at different periods. The East wing, to the left when looking at the basilica, dates from 1295, the same time as the Basilica.

Upstairs, the cell windows were made bigger in the 18th century. The North wing dates from the 14th century; it is more substabtial because of its ornamentation and its dimensions. A superb painted sundial can be seen on the second storey.
