Answer 1

I can’t see the photograph you mean. Please upload the image or describe it. Meanwhile here are quick ID tips (and the letter mapping):

- A = corbel vault: stepped/overlapping stones or bricks that project inward in tiers to form an arch-like roof. Looks like stacked ledges, not a smooth curve.
- B = onion vault: bulbous, onion‑shaped curved profile (like an onion dome in vault form).
- C = barrel vault: a continuous semicircular tunnel shape — a smooth half‑cylinder running along the length of the space.
- D = groin vault: formed by the intersection of two barrel vaults at right angles; you’ll see an X or diagonal ridgeline (groins) where the vaults meet.

If you upload the photo (or describe which of these features you see), I’ll pick the best answer.
