Roman market building in Puteoli (Pozzuoli). Because of bradyseism there are deposits of shellfish visible on the columns. The earth is at this place regularly on the move, sometimes rising, sometimes falling, making that the Macellum sometimes is under water and sometimes dry. Puteoli/Pozzuoli is situated in the Campi Flegrei, the caldera of a supervolcano.
