The philosopher and mathematicianHypatia was murdered at the Caesareum by a Christian mob in 415; they stripped her naked and tore her to pieces.[5]
Elements of the temple survived until the 19th century. Cleopatra's Needles, two much earlier obelisks moved to the temple in ancient times, now stand in Central Park in New York City and on the Thames Embankment, in London.[3][6] The underwater archaeological work of Franck Goddio and the European Institute for Underwater Archaeology (IEASM) in the eastern harbour of Alexandria[7] has added to the knowledge about the Caesareum. An article "The Caesarium",[8] published in 2021, reveals that the groundworks were started prior to the reign of Cleopatra VII. It also considers the building's relationship with the harbour based on ancient texts and the position of Cleopatra's Needles and it provides some indications about the siting of the temple itself.
Today, a large statue of the Alexandrine nationalist leader Saad Zaghloul (1859–1927) stands on the Caesareum site.
