Jerusalem has run out of burial space -- so they are digging deeper

The holy city of Jerusalem has run out of grave plots. So they are digging deep underground to solve their burial space problem.

The company Rolzur Tunneling has begun digging an underground cemetery beneath the city's main cemetery to add 22,000 graves below the surface, according to the Washington Post.

Rolzer chief executive Arik Glazer said, "We came up with this idea to provide a solution under the cemetery with burial structures, but also hidden from the eye."

"Burials like this existed in ancient times, 1,600 to 2,000 years ago, and we have we have revived this tradition because of the lack of burial space," Glazer added.

The "city of the dead" will have tunnels with elevators and walkways that will give families easy access to deceased loved ones.

The project even finished as runner-up for the 2017 International Tunneling Underground Space Association’s "Concept of the Year."

The $50 million project is expected to be finished by the end of 2018.
