Paris Catacombs History

Key Milestones in the History of the Paris Catacombs

The Catacombs of Paris originated in the 1st century when the Romans mined limestone beneath what is now the city.

These ancient quarry tunnels would later become the foundation of one of the most unusual ossuaries in France.

This marks the earliest phase in the history of the Catacombs in Paris.

By the 18th century, Paris faced serious issues from overcrowded cemeteries like Saints-Innocents.

The unsanitary conditions triggered disease outbreaks, prompting authorities to act.

This health crisis played a pivotal role in the Paris Catacombs' history.

From 1785 to 1787, remains from over 150 cemeteries were moved to abandoned quarry tunnels.

This transfer created the first version of what we now call the Parisian Catacombs.

In 1809, the site officially opened to the public as the Catacombs of France.
