Take in the grandeur of Cattedrale di San Giacomo. Go to a service if you can or just take a seat and appreciate the serenity.
This principal church is in Tuscania, a destination that has plenty of things going for it! National Archaeological Museum of Tuscania, Church of Santa Maria Maggiore, and Torre di Lavello Park are other good sightseeing options close by when you're all done at Cattedrale di San Giacomo.
