Interesting facts about the Paris Catacombs

For over 30 years, the often-flooded underground tunnels have attracted daring divers. Known by the codename Plongeur, one Parisian cataphile has fearlessly explored uncharted galleries, assisting the Department of Quarries in mapping these hidden passages.

Mushroom farming became one of the Catacombs’ most unusual uses. After mining ceased in the 19th century, a quarryman discovered mushrooms thriving in the dark, humid underground. This chance find led to the cultivation of the iconic Paris mushrooms.

Thieves in the 1800s often disguised themselves as tour guides, leading unsuspecting visitors deep into the Catacombs to rob them. Victims were left to navigate their way out alone. To prevent disorientation today, a thick black line, known as the lifeline, is painted along the ceiling, guiding visitors safely to the exit.

The bones in the Catacombs aren't randomly piled; they're carefully arranged into shapes like crosses and hearts. This macabre display creates a unique art form, blending reverence with aesthetic design. A notable highlight is The Barrel of Passion.
