The Obelisk of Montecitorio (Italian: Obelisco di Montecitorio), also known as Solare, is an ancient Egyptian, red granite obelisk of Psamtik II (595–589 BC) 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 21.79 metres (71 ft) high, and 33.97 metres (111 ft) including the base and the globe.
