Went in at first light with two others. The main hall is more intact than the photos suggest — the collapse everyone posts about is confined to the east wing. Floor is sound if you stay on the joists. We were out in ninety minutes and saw nobody.
Place Denfert-Rochereau: the tollhouses, the lion, and the door down.

The record
Former limestone quarries converted from 1786 to receive remains from Paris's overflowing cemeteries. Roughly 1.5km is open as a museum; the wider network runs some 200km and is closed to the public.
The oracle
sign in to retell
You smell it before you see it — wet concrete, iron, something older. Catacombes de Paris does not announce itself. What registers first is scale — the structure is larger inside than the approach prepares you for, and colder.
Paint has come off the walls in sheets, curled like bark. The known history covers perhaps two thirds of what you are standing in. Beyond that the record thins into municipal paperwork and hearsay, and then into nothing at all.
The building's own plans, where they survive, describe one more room than anyone has found. At danger level 4 of 5, the honest advice is that the place deserves more caution than curiosity usually allows.
Site reconstruction
Walk inside Catacombes de Paris
You arrive outside. Orbit the site, fly over it or walk the grounds, then go in — four fragments of this site's record are scattered through the structure, and your torch runs down the whole time.

Generated from this site's record — a underground of its scale and condition. Its character, not its surveyed floor plan.

Written by people who actually went. Where these contradict the oracle, believe these.
Permit came through in about two weeks. Guide was excellent and let us set up properly rather than herding us. Worth doing it the legitimate way — you get access to the lower level, which the fence-hoppers never see.
