Catacombes de Paris

The Catacombes de Paris are an extensive network of underground tunnels and ossuaries beneath the city, historically used for limestone quarrying. In the late 18th century, they were repurposed to house the remains of millions of Parisians displaced from overcrowded cemeteries, creating a unique underground mausoleum. Spanning about 200 miles, these tunnels feature neatly arranged bones and skulls, offering a fascinating glimpse into Parisian history, burial practices, and urban development. Today, they serve as a popular tourist attraction, blending history, architecture, and a reminder of the city's layered past.
