Join Billy and Nick as they dive into the catacombs of Paris, France. Originally created in the late 18th century, the catacombs were formed as a solution to the city’s overflowing cemeteries, transferring the remains of millions beneath the streets of Paris into a vast and eerie tunnel system.

Billy and Nick tackle the history, the spooky tales, and some of the things urban explorers should be wary of as they attempt to illegally tour one of France’s most historic—yet haunting—locations hidden deep beneath the City of Light.
