The history written in the introduction does not specify which period it belongs to. This is a big shortcoming. My guess is that it may belong to the Hittite Period. I think only 5% to 10% are open for visits. Dec. Because there is only a stable, a winery and a kitchen part. If this is a city, I think it should be much bigger.
I have a few warnings for the visitors. It is a very challenging place for those with claustrophobia, those who are overweight, those who have waist problems, those who are tall and those who are afraid of staying in a tight space. Because the rooms are constantly provided with passages half the height of a person.
Larger and wax sculptures and period settings could have been much more attractive.
It can be finished in half an hour at the slowest state. It gives a FRP game feeling inside. Also, do not enter through the doors in the barn section. Because there is no way out.
The Museum Card is valid.
If you don't like enclosed and small spaces, then you definitely shouldn't go on an excursion to this underground city.
And in general, it is not a very comfortable place and not a very interesting tour
