The Colosseum is located near the ancient Roman market in the centre of Rome. The original name of the Colosseum is the Flavi amphitheatre. It was built between 72 and 80 A.D. for the slave owners, nobles and free people to watch the beast fight or the slave fight. It is a miracle in the history of architecture and represents the most obvious characteristics of ancient Roman civilization. The Colosseum is oval, covering an area of about 20,000 square meters, with a long axis of about 188 meters and a wall of about 57 meters high, which can accommodate nearly 90,000 spectators. Inside, you can watch the sections along the visitor's pavement. The auditorium is ladder-like, the outermost layer is the arcade, which is the rest area before the audience enters the venue. Modern gymnasium design is completely copied from this. The thick and sturdy arcade shows the sculptures of that time. At the bottom of the arena are grooved feeding areas, combat preparation areas, diversion channels and so on. Now they are completely exposed and tidied up, and formerly they were covered with broad fighting platforms. Although the Colosseum is only half of the ruins, it still reproduces its magnificent momentum.
