Overview
- The Paris Catacombs reopened after a five-month project that improved conservation, ventilation, and lighting.
- Restorers stabilized bone walls by placing long bones at the front and stacking rounded bones behind them to hold the structure.
- Site managers say the limestone tunnels stay very humid and keep shifting, so crews will continue to shore up and maintain the galleries.
- Access now requires online reservations made seven days ahead, with 2,000 tickets a day, demand three to four times higher, and no on-site sales.
- About 20 meters below the city, the ossuary holds remains moved from Paris cemeteries between 1786 and 1814 and now draws roughly 600,000 visitors a year.
