Second visit, three years after the first, and the difference is grim. Water has got into the upper floor and taken the ceiling with it. Whatever you were planning to photograph here, do it now or don't bother.
The plateau town above it: the entrance, the vent shafts, and the tuff cones.

The record
A multi-level subterranean settlement cut into soft tuff, reaching roughly 85 metres deep. Capable of sheltering some 20,000 people with livestock and stores. Rediscovered in 1963 when a resident broke through a wall of their house.
The oracle
sign in to retell
You smell it before you see it — wet concrete, iron, something older. Derinkuyu Underground City does not announce itself. What registers first is scale — the structure is larger inside than the approach prepares you for, and colder.
Water has found its own routes through the structure and made them permanent. 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 2 of 5, the honest advice is that the place deserves more caution than curiosity usually allows.
Site reconstruction
Walk inside Derinkuyu Underground City
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.

Written by people who actually went. Where these contradict the oracle, believe these.
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.
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.

The AI mythos is a bit much for me but the timeline is solid.
Reminder that this one is genuinely protected, not just fenced. Fines are real.
Whoever wrote this dossier has clearly been. The hazard list is exactly right.
