Underground cave-city found

[Mikail2730]

Hello everyone.
Approxematly 9 months ago (in July) my family and I went on a vacation to Turkey. During our visit we went to the mountains where we found an enormus hidden cave. The entrance had man made "doors/openings", window like holes, and both big and small tunnels. We went about 200 meters inside the tunnels were we saw atleast 5-10+ rooms before we decided to head back. On top of the "door"-openings some type of script is carved into the mountain.
I hope some of you have some expertise within this subject, and that you can help me finding out what era this cave is from, and some other things.
Next year I will make sure to go inside the rooms and look for possible "treasures" .
The cave is located in the Anatolia region of Turkey. Thank you.

(IMPORTANT: a few kilometers away from this cave a tall hill/mountain is located, on top of that mountain we found some "weird" shapes, in what i believe is marble, does Anyone have any idea what it is?)

Update:

Here is a video of an archaeologist examining the Cave.
And the so called hill was actually a burial mound.

He sais it resembles the underground cities of Cappadocia, and that it is more than 3 stories tall and has a big turism-potential.
