The tens of thousands of bees living on Notre Dame’s roof survived the horrific fire that overtook the famed cathedral earlier this week.

Bees have been buzzing atop Notre Dame since 2013, when three beehives with about 60,000 bees each were put on a roof over the sacristy. The flames that engulfed the cathedral miraculously didn’t touch the bees because they’re about 30 meters below the main roof where the fire was.

Notre Dame officials spotted the bees on top of the sacristy on Friday, buzzing about their business.
