Located next to the Fillols Gate there is a chapel from the late 14th century. This is again the foundation of a bishop, Guerau de Requesens. Unlike the other large chapels, the chapel of Requesens has retained a rich sculptural decoration spread over all the ribs of the vaults, where the family heraldic combines with figures of various saints. Also worth mentioning are the three keystones, authentic carvings in stone. Although the tomb of the founding bishop is not preserved, fragments from the tomb of one of his descendants are preserved.
