Dargavs is a small necropolis outside the village of Dargavs in North Ossetia-Alania. It comprises 99 different tombs and crypts. It is often called city of the dead. Some sources say the oldest of the crypts dates back to the 12th century, though others say the oldest crypt dates back to 14th century and some say it dates to the 16th century. At the back of the complex there is a tower, though the top of it is destroyed.

The population is densely concentrated in the east and accessibility is increased, whereas rural provinces in the west remain remote.
