 The church is an imposing Romanesque structure situated high on the hill which the city climbs, but it lacks much of the spectacular decoration with which it was originally adorned, thanks to an ill-advised sixteenth-century reconstruction.According to legend, the cathedral was built on the site of an Etruscan temple of Hercules.Etruscan and Roman foundations can be seen on several of the buildings facing the Piazza di San Lorenzo where the cathedral is situated.
