Domenico Fontana
In the 9th century, it was enclosed in a fortification area. The interior was largely renovated by Domenico Fontana in 1587 and by Francesco Borromini in 1643. Italian architect and art historian Antonio Muñoz restored the original medieval appearance of the church (which had served as a lazaretto since 1870). The bell tower was built in the 10th century and remade in the Baroque period.
