Located in the center of Rome, the circular square. The front of the square is a neoclassical building built in white marble, nicknamed "wedding cake" 😂, it is really a bit like ~ It is said that the curved facade formed by 16 cylinders is its most wonderful part. There are two sets of fountains under the steps. ⛲ is also very beautiful. If you want to take a panoramic view, you may be close to the road, pay attention to safety.
