Our guide was VERY knowledgeable and I enjoyed the details he provided for why historical things happened as they did at this parish church turned basilica. The “whys” and personalities of historical figures are sometimes the best part! Access to an actual catacomb is very special but all of the actual tombs, except one, are sealed so the picture advertising the tour, though accurate, didn’t look like the real thing, as it wasn’t colorful at all. It’s an opportunity to see something unusual and our guide had the answers to all sorts of great questions. I learned a lot and would definitely recommend this tour.
