The Roman People's Square, built in the 17th century, is the convergence point of three radial trunk roads. It is oval. In the center, there is an obelisk from Egypt, 23.2 meters high. It is the landmark building of the square. The north side of the square is the People's City Gate, the south side has two symmetrical churches built at the same time, the right side is the Notre Dame of Miracles, the left side is the Notre Dame of Mount Notre Dame, the square also has fountains and lion sculptures. Square gives people a sense of freedom and openness of space. On the day we went to the square, the obelisk was enclosed in a square pillar shape by an art mask, which read a famous saying of Patrick Milan, a contemporary French multimedia artist: if beauty is subjective, ugliness is objective. It may be the decoration of art exhibition advertising activities, or the covering decoration of repairing the obelisk.
