The Lateran Obelisk 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).[1][2] It is located in Rome, in the square across from the Archbasilica of St. John Lateran and the San Giovanni Addolorata Hospital.
