#2: Catacombs of Paris — France
Underneath Paris’ streets lies a city made of bones. Starting in 1786, officials moved remains into a network of old limestone quarries to address overflowing cemeteries. The tunnels now hold the skeletons of roughly six million Parisians. The first remains came from the city’s largest cemetery, Saints-Innocents, a process that took two years. The ossuary opened to the public in 1809, and people have been fascinated ever since. Walking through corridors lined with skulls and femurs, you see history arranged in a way that’s both orderly and deeply unsettling.
