Paris catacombs - Spiral entrance stairs

One of the catacombs entries. Convenient entries like this one are pretty rare, and usually locked (being only used by the police and the Geological Inspection Dept (*Inspection Générale des Carrières*). Most of the catacombs galleries in the *Grand Reseau Nord* are about 60 ft beneath the surface, though there are galleries that run even deeper (down to 90 ft deep). Scanned with the iPhone12 Pro and Scaniverse. Please feel free to follow my collections of daily scans ([link](https://skfb.ly/6YuwK)) as well as my scans in San Francisco, Paris, or in the catacombs: [link](https://sketchfab.com/edemaistre/collections)
