This single nave building was founded in 1607. Here the foreign catholic countries built their altars. Inside, the six early 17th century altars were made on the model of the elder one (of the French), which keeps the representation of "Saint Louis king of France" painted by Matteo Rosselli between 1613 and 1614. 
On the altar of the Corsica (about 1620-1630) is represented "Saint John Evangelist" by Francesco Curradi. On the Flemish altar it is represented "Saint Andrew apostle" attributed to Giovanni Bilivert. The Portuguese altar is dedicated to "Saint Anthony from Padova". On the high altar there is a statue of the "Madonna" (16th century). Above the altars there are eight representations of "Scenes of the life of Saint Anthony from Padova" (18th century).
