Dedicated to St. John the Baptist, the protector of Florence, the new church for the Florentine community in Rome was started in the 16th century and completed in the early 18th, and is the national church of Florence in Rome.
It was lavishly decorated with art over the 16th and 17th centuries, with most commissions going to Florentine artists.
