This basilica is one of the largest in Rome and one of its five patriarchal basilicas, where the pope offered Mass at certain festivals. The cover is not too dramatic, baroque style, the most striking may be the medieval tower that rises 75 meters from the ground, being the highest of Rome.

The outside is perhaps the most beautiful of the apse, which overlooks the Piazza Esquilino, from where you can better see the domes of the Sistine and Pauline Chapels, which give the whole a great sense of balance. Inside the basilica is impressive, with a high coffered ceiling of the nave. In the background, facing the altar, a canopy recalls that of San Pedro and the right of this is the tomb of the master Bernini, marked by a discreet marble slab.
