The Serapeum of Alexandria in the Ptolemaic Kingdom was an ancient Greek temple built by Ptolemy III Euergetes (reigned 246–222 BCE) and dedicated to Serapis, who was made the protector of Alexandria. There are also signs of Harpocrates. It has been referred to as the daughter of the Library of Alexandria. The site has been heavily plundered.
Pompey's Pillar (Arabic: عمود السواري) is the name given to a Roman triumphal column in Alexandria, Egypt. Set up in honour of the augustus Diocletian between 298-302 AD, the giant Corinthian column originally supported a colossal porphyry statue of the emperor in armour. It stands at the eastern side of the temenos of the Serapeum of Alexandria, beside the ruins of the temple of Serapis itself. The erroneous name and association with Pompey stems from historical misreading of the Greek dedicatory inscription on the base.
