Discovered purely by accident in 1900 when a donkey fell through an access shaft, this is considered one of the Seven Wonders of the Middle Ages. It is a massive Roman-era necropolis carved deep into solid rock, featuring a highly unique blend of Ancient Egyptian, Greek, and Roman architectural styles and artwork.

• What Tourists Actually Search For (Tips & Hacks):

  • Claustrophobia and Accessibility: The number one logistical search is about the descent. You enter the catacombs by walking down a dimly lit spiral staircase that encircles a central well (originally used to lower bodies with ropes). It is completely underground, damp, and not recommended for travelers with severe claustrophobia or mobility issues.

  • The Flooded Bottom Level: Tourists often ask why they can't see the entire complex. The lowest level of these catacombs is permanently submerged in groundwater and inaccessible, so visitors only tour the top two levels.

  • Photography Rules: While photography is now generally allowed with a smartphone, flash photography is strictly prohibited. The flash can degrade the unique, ancient pigments of the subterranean artwork over time.
