The Egyptian Obelisk of Piazza S. Giovanni in Laterano in Rome, Italy, was previously located at the Circo Maximo by emperor Costanzo the IInd; it was positioned at the current location in the XVI century by the architect Domenico Fontana. The obelisk stands on a 10m tall basement and, considering also the crux on the top, the total height of the monument is 45 meters. An extensive campaign of six months ambient vibration monitoring, sonic tomography and radar investigation has been carried out by ENEA for the structural evaluation of the obelisk.
