Paris has great catacombs that you can tour small sections of. Well over 5 million Parisians are buried there. From those killed by the guillotine, to the dead of the French Revolution, to those dis-intered from the over flowing Saints-Innocents Cemetery which was the largest in Paris at the time.
The famous sign at the entrance says “Arrête, c’est ici l’empire de la mort.” — Stop, this is the empire of the dead.
The skulls and bones were often arranged in designs and patterns and form walls throughout the catacombs.
