The historic pipe organ dates from the beginning of the 17th century and contains 321 pipes.
The oldest structural parts of it, though, date back to 1479.
The church roof previously collapsed over the organ, leaving it exposed to harsh weather conditions.
In 1994, Fratelli Ruffatti firm completed a succesful historical restoration, bringing the instrument back to life.
