On the counterfaçade, to the right of the the entrance portal, is a monument to the Florentine artists Antonio Pollaiuolo (Antonio di Jacopo d'Antonio Benci), (c. 1432-1498) and his brother Pietro (c.1441-c. 1496), the work of Luigi Capponi (c.1500). The brothers worked as painters, scupltors, and goldsmiths in Florence. The greater artist of the two, Antonio made the figures of Romulus and Remus beneath the Lupa Capitolina, long assigned to the 5th century BC but now dated to the age of Charlemagne.
