Imagine a church so big it was the largest in the world for five centuries until St. Peter's took the crown. Most of the original structure is gone, but the remaining bell tower and transept are still towering. Spend two hours here; the 3D screens help you visualize the missing bits. If you want the deep lore, book a private guide to explain the Benedictine power trips, otherwise, grab the $8 audio tour and wander the quiet village streets.
