What does a quarter of a million euros worth of wine look like? You’re about to find out.

This week, it was revealed that thieves drilled through walls in the catacombs of Paris in order to break into a private wine cellar to steal €250,000 worth of vintage wine. The catacombs, most of which are off limits to civilians, cover about 250 km (155 miles) of tunnels underneath Paris, and are home to some of the city’s most grotesque lore. Filled with six million Parisian skeletons, the tunnels likely have a lot of curious goings-on, and more than a few mysteries waiting to be uncovered.

“The suspects didn’t drill that particular wall by accident,” said one police spokesman. The criminals likely belong to a small group of cataphiles, or curious individuals who enjoy burrowing around in the catacombs looking for hidden treasures and secret entrances. Or, in this case, 300 bottles of rare vintage vin. Somewhere in Paris, these thieves must be throwing one wild party.
