Enjoyed our tour last weekend (Nov 2022). We are not Catholic, but the tour had plenty of general information/history to make it interesting. Of course, the part we were most interested in was the catacombs, and it did not disappoint. It was not the exposed-bones-piled-on-top-of-each-other type catacomb you find in places like Paris, but fascinating nonetheless. Sadly, we were not able to go behind/into the massive organ- apparently too much visiting in the past was not good for it and they are currently trying to raise money to refurbish it. I just wish they wouldn’t advertise such on their website, now that it’s not part of the tour. Enjoyed our visit.
