The Temple of Serapis . This magnificent temple comes from a cult introduced from Alexandria by the Romans as early as the IInd century BC. This temple had been restaured under Caligula. Built on the top of the Quirinal, two steps away from the Baths of Constantine, it must have been visible from anywhere in Rome. Two great porticoes framed the Temple.









On the slope of the Quirinal, a great portico was attached to the Temple of Serapis, Portico of Constantine.
