The Serapeum of Alexandria in the Ptolemaic Kingdom was a ancient Greek temple built by Ptolemy III Euergetes (reigned 246–222 BCE) and dedicated to Serapis, who was made the protector of Alexandria. By all detailed accounts, the Serapeum was the largest and most magnificent of all temples in the Greek quarter of Alexandria. Besides the image of the god, the temple precinct housed an offshoot collection of the great Library of Alexandria.[1][2] The geographer Strabo tells that this stood in the west of the city. Nothing now remains above ground.
