Ossuary Church of St. Matthias

The oddity, explained

Why is Ossuary Church of St. Matthias unusual?

Ossuary Church of St. Matthias appears here because the approved source classifies it as heritage. The source describes it as ossuary and part of an architectural ensemble in Steinhausen in the canton of Zug, Switzerland. Heritage Atlas treats that specific classification-and-description combination as the oddity; the score is a comparative discovery signal, not proof of mystery or the supernatural.

Evidence and further exploration

The coordinate, category and description remain tied to the cited source. Comparative oddness helps discovery; it does not add facts that the source does not provide.
