The Obelisk of Montecitorio, also known as Solare, is an ancient Egyptian, red granite obelisk of Psammetichus II from Heliopolis. Brought to Rome with the Flaminio Obelisk in 10 BC by the Roman Emperor Augustus to be used as the gnomon of the Solarium Augusti, it is now in the Piazza Montecitorio. It is 21.79m high, and 33.97m including the base and the globe.HistoryFirst constructionAugustus erected it as the gnomon of the Solarium Augusti, his giant sundial (or horologium) in the Campus Martius. The meridian, worked out by the mathematician Facondius Novus, was placed in the center of a surface measuring 160by, constructed from slabs of travertine, on which a quadrant was marked out with bronze letters, with indications of the hours, months, seasons and signs of the zodiac. Besides its function as a solar clock, the obelisk was oriented in such manner so as to cast its shadow on the nearby Ara Pacis on 23 September, Augustus's birthday, which coincided with the autumnal equinox.
