The Lateran Obelisk (Italian: Obelisco Lateranense; Latin: Obeliscus Constantii) is the largest standing ancient Egyptian obelisk in the world, and it is also the tallest obelisk in Italy. It originally weighed 413 tonnes (455 short tons), but after collapsing and being re-erected 4 metres (13 ft) shorter, now weighs around 300 tonnes (330 short tons). It is located in Rome, in the square across from the Archbasilica of Saint John Lateran and the San Giovanni Addolorata Hospital. The obelisk was made around 1400 BC in Karnak, Egypt, during the reigns of Pharaohs Thutmose III and Thutmose IV. Roman Emperor Constantine I had it moved to Alexandria in the early 4th century AD, then Constantius II in AD 357 had it shipped to Rome and erected at the Circus Maximus. The obelisk collapsed and broke into pieces sometime after the Circus's abandonment in the 5th century and became buried. It was excavated and restored by Domenico Fontana in the late 1580s, and by the order of Pope Sixtus V was topped with a Christian cross and installed in its present location near the Lateran Palace.
