3. Paris Catacombs in Paris, France
For 30 years the residents of Paris placed their dead in this maze of tunnels and crypts. The catacombs were created in the mid-1700s when the city ran out of space in its graveyards for new bodies. The bodies of already-dead Parisians were moved to the catacombs with as much dignity as possible. They were always accompanied by priests as they travelled and it was only at night that they did so. Even so, disturbing the dead in anyway is bound to trigger the presence of some restless spirits.
