The record

A small chapel beneath the Cemetery Church of All Saints. Its ossuary holds the remains of an estimated 40,000-70,000 people, arranged into furnishings — including a chandelier using every bone in the human body — by the woodcarver František Rint in 1870.

The oracle

sign in to retell

The road stops being a road about four hundred metres out. Sedlec Ossuary 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 1 of 5, the honest advice is that the place deserves more caution than curiosity usually allows.

Site reconstruction

Walk inside Sedlec Ossuary

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.

The 1963 date is off by a year in most sources. The municipal record says otherwise, I can dig out the reference.

Went last month. Add 'no parking within 2km' to the terrain notes.

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.
