Nope, still impressive as hell! That's a whole ass underground city, with ventilation, space for livestock, etc. Definitely somewhere I'd absolutely love to explore. I'd still love to understand how and why it was first made. Why did they think about having livestock down there. How old it actually is.

It seems to date back to the 800s BCE at the earliest, a period of time where advanced construction was abundant given that cities like Athens and Troy were established during this time.

I think the reasoning behind having constructed it was to have a way to hide and defend from invaders, given that Anatolia (the region now known as Turkey) has been the battleground for numerous different peoples for thousands of years (first the Greeks took it, then the Persians, then the Greeks again, then the Macedonians, then the Romans, then the Muslims).

Another thing that helps make sense of the place is that it wasn’t built at the same time. It was expanded upon over hundreds and thousands of years, again it was used by the local Christian population to hide from the Muslim government in the 1920s. It’s a much more modern site then you’d think it was.

Still impressive though just not as mysterious as some would believe.
