Now flooded, an ancient latrine uncovered in the macellum (food market) of ancient Puteoli (modern Pozzuoli, Italy) was an elegant public facility when it was constructed 1,800 years ago. The water table below the structure has fluctuated over the centuries as a result of what geologists call bradyseism, a term used to describe the rise and fall of land surfaces in volcanically active areas.
