Obelisk from St. Peter's Square

St Peters Square with obelisk, originally uploaded by Gauis Caecilius.

The obelisk in St. Peter's Square originally stood in Nero's circus (where St. Peter was crucified) and it is inscribed with Latin letters, not hieroglyphics. It was brought to Rome from Egypt by Caligula in 40 AD. It was buried in obscurity for many centuries until Pope Sixtus V had it raised at its present site - requiring the work of 907 men, 75 horses and 40 winches.
