Inside the main entrance is a vestibule which leads to the main courtyard of the cloister. This area is plainer than the porteria, with only black and white 16th-century frescos adorning the walls and some gray gargoyles on the upper parts of the columns. Many of the frescos and gargoyles are now fragmentary. The cloister has two floors and courtyard surrounded by 20 arches supported by Tuscan columns. The ceilings are made from large wood beams and the floors are paved in local stone. On the north and south sides of the upper cloister there are two sundials. One is meant to be used in the summer and the other in winter.
