In the right transept is the Visconti tomb, and a door leading to the lovely small cloister of russet terracotta, with a fine view of the church's galleried octagonal tower.
You can get a great view of the tower of the church.
There is a marble statue of Julius Caesar, consort of Queen Cleopatra, who spent many months here, and a bust of Alexander, which was carved in his likeness after his death.
