The village of Dargavs in North Ossetia (a subject of Russian Federation) has a mystical necropolis also called the city of 10 000 dead. 96 crypts keep ancient secrets for many years. Even now this scary place is still shrouded in mystery and no one really has reliable information about the biggest necropolis of Caucasus.
Be careful though, you are going to see some skulls and mummies in this post.
