Question

Which Catacombs of Rome are worthy? wher are located?

Answer 1

Yes, they are! There are more than 50 catacombs in Rome, but only five are open to the public. They are very interesting places to visit, real underground mazes, and if you are lucky enough to have a good guide, you'll learn lots of things. The Catacombs of St. Callixtus are the biggest and possibly the most popular. It's very easy to get there.They are on the Via Appia Antica.
