The Circus Maximus can be considered the biggest circus ever built. It was 600 meters long and 140 meters wide and it could host 250.000 people. It was built in the 6th century B.C. In the 1st century B.C. Augustus placed in the central part of the circus the obelisk of Rhamses II which today dominates Piazza del Popolo. In the year 357 A.D. it was placed at the centre of the circus another obelisk, the highest one in Rome, which can be admired today in Piazza San Giovanni in Laterano. Both obelisks were stolen by the romans during the occupation of Egypt and both of them reused to decorate two beautiful squares.
