Each year, the macabre display attracts more than one million visitors, who bravely descend into the dark tunnels via narrow steps. Those who are gutsy enough to make the journey should expect damp conditions, with an average temperature that hovers around 59 degrees Fahrenheit. Upon arriving at the ossuary, visitors will be greeted with the haunting inscription: “Arrête! C’est ici l’empire de la mort” (Stop! This is the empire of death). Just keep in mind that a maximum of 200 people are permitted into the tunnels at a time, and queues to enter can be long. Still, it’s a must-see for anyone who’s fascinated by morbid attractions. And although it might not fall along the traditional tourist-trodden path, the bone-lined walls are unlike anything else you’ll experience in the City of Love.
