During a home renovation In 1963, a man in the Nevşehir Province of Turkey demolished an interior wall of his home, and he found a secret room leading to something that would’ve made Indiana Jones proud. His discovery was a secret underground city, reaching up to 18 stories beneath the Earth, complete with ventilation shafts, protected water wells, and rooms large enough to hold Sunday sermons!
How did they do it?
Seriously though. However it was done, building an 18 story underground city with such precision is an impressive feat. Here’s what we do know.
Historians estimate that the city was built around 8 BCE, and was used and even expanded for thousands of years. It was a handy place to defend against invading armies.
