Three Egyptian obelisks were erected in London, New York and Paris during the 19th century. London’s can be found on the Victoria Embankment, some distance away from its original site in Heliopolis in Egypt in 1450 BC, which makes it over 3,000 years old. It has little to do with Cleopatra, as it was originally made for Pharaoh Thotmes III.
It was transported to London to commemorate Nelson’s victory over Napoleon, even though the events on the seas took place over 60 years earlier. William James Erasumus Wilson funded the project and it has remained in place on the banks of the Thames ever since.
