Excited to see what will come from this study over the next years, this was my favorite place to see in Paris last year, and wasn't too hard to schedule the visit (I think I booked one or two days before). Some sections are closed, and I read the catacombs are not fully mapped. Wondering if they will find something or someone long thought to be lost down there.
