 Later also, the Treasury chapel was built in 1691 in the Baroque style by Filippo Parodi, a pupil of Bernini.Externally, the brick facade has a Romanesque central section which was extended outwards when the aisles were built, acquiring in the process four deep Gothic recesses and an elegant arcaded balcony which stretches across the broad front of the building.The facade gable shows little differentiation between the nave and aisle, screening the very large buttresses that have the same profile and form a richly sculptural feature when the building is viewed from the side.
