10 Lost Cities Of The World

I'm surprised that the Derinkuyu and the other underground cities of Capadoccia aren't better known.

I'm surprised that the Derinkuyu and the other underground cities of Capadoccia aren't better known.

I'm not, but Derinkuyu was right there at #3 on the list in the OP.
