Originally it had two side doors with the figures of St. John Baptist and St. Sebastian, that are now located in the National Museum of Castel Sant’Angelo in Rome.
There is also a very interesting fresco by Giovanni Antonio de' Sacchis, called Pordenone, commissioned in 1516 by the widow of Bartolomeo from Alviano, Pantasilea Baglioni, representing the noblewoman herself as well as a Virgin with Saints.
