It is known as the most beautiful square in Rome. Whether it is day or night, it is an ideal place for people to spend a couple of hours in a cafe and enjoy the crowds in the past. The outline of the square is a broad oval shape. There are three famous fountains on the square. They are the Moorish fountain at the southern end of the square, the Sihe fountain in the center, and the Haishen fountain at the northern end of the square.
