Derinkuyu is, absolutely astonishing! How did they build it?! Just, how?! We lost so, so much when the library of Alexandria, and I think there were so many answers there. Maybe some day we'll find another hidden place with answers.

I mean Derinkuyu and the other underground cities of Turkey are impressive but they get less mysterious when you realise that the people of that place have been using them and expanding them up until the 1920s.
