This place is miles from your typical Parisian promenade.
Follow the stairs down into a tunnel which houses this 18th century ossuary. The extensive pathways are lined with lined with masses of skulls and bones. Prepare yourself to be seriously creeped out: you’ll feel as though you are in a crossover episode of The Vampire Diaries and Pretty Little Liars.
To reach the exit (on the other side) and become sufficiently freaked out, it took us 45 minutes. Note: The queue around the square is incredibly long (and slow!) so be sure to get there early.
Now, I suppose I’ll let the photos do the talking…
