We visited the Kaymaklı Underground City. It is this huge underground city that the ancients dug underground. The ground they dug should not be imagined like the one we have in singapore though. This one is made of rocks that are strong enough to hold the structures but soft enough to dig using anything sharp. I think even a pen can carve out a room if you are given enough time.
Only four of the 8 floors are opened to tourists. There are ventilation shafts to ensure that fresh air can get it. There are even underground stables, a church, toilets, kitchens, and bedrooms of course.
This picture below shows a stable. See how they have carved a place for the horse to eat grass, hay or whatever they feed their horses with?
This photo below shows how deep the tunnels can bring the inhabitants of these caves into the earth below. The labyrinth also allowed them to hide from the people that might want to hurt them.
This is a huge heavy stone that they use to block some strategic entrances within the city so that their pursuers could not get them.
Last, but certainly not the least important... toilets! I really do not know if they just leave it there or what, for they did not have any flushing system.
