The main part of the organ is in an aedicule inserted into the apse, which has doubletted pilasters matching those flanking the entrance. These support a triangular pediment raised on posts, into which is inserted a large coat-of-arms which breaks the cornice. The organ itself is a very fine instrument, built in 1936 by Tamburini di Crema. On either side, over the last bay of the nave, are a pair of gilded cantorie or opera-boxes for solo musicians.
