We toured an underground cave that they believe to have been used by the early Christians fleeing invading armies. These tunnels and living spaces were a huge network of passages and deep containment spaces. There were several levels that you could go from one to the other but there were also holes cut out for communication and for transporting objects from one level to the next. It was really amazing how each tunnel was connected from living to cooking to storage and worship spaces. They even developed a plan to battle against oncoming invasions from behind the massive boulders that they used to close off passageways.
Steve got stuck in this hole-not really, but it was really funny.

This was the
best place for this motley crew!

I can't remember how many meters this "well" was but it served as venilation to the surface air also. One of the guides dropped a coin down in it and we never heard it hit the bottom.
