The Temple of Serapide is not a temple but it’s a macellum (market) of the I-II century AD. The macellum is well preserved, thanks to bradyseism (volcanic activity that increases and then decreases the level of the city compared to the sea) of the city of Pozzuoli.

The macellum was initially confused with a temple, because during the first excavations a statue of the Egyptian god Serapide was found in the area.
