Yeah, the tunnel’s in the old service‑shaft plans in the city archives, but it’s marked as “abandoned” and the only thing there is a rusted stairwell. The legends usually start with someone spotting a faded graffiti tag that says “Bazar 42” in cracked tiles. No real map, just a bunch of half‑baked rumors from street vendors who swear they’ve seen a flicker of lights in that shaft. The best clue I’ve found is a postcard from a tourist in the 80s that shows a narrow, lantern‑lit passage with a “forbidden” sign—probably a hoax, but it’s the closest thing to a map. If you’re serious, ask the local subway archivist; he might have an old service map that shows a hidden switch in that shaft. Good luck, but don’t expect a treasure trove.

Sounds like a perfect recipe for a night of urban spelunking and a lot of dead ends. Just remember, the city’s “secret market” is probably a rumor stitched to the underside of a forgotten platform, not a glittering bazaar. Still, the thrill of chasing a ghost map beats a quiet coffee any day. Good luck, and bring a flashlight and a notebook—those rumors usually have a footnote.
