The Prague City Hall is the tower where the Astronomical Clock is located and the two amazing houses next to it. The Gothic tower was completed in 1364 and has a cloister at the top to buy tickets to overlook the city of Prague. The most famous is the astronomical clock, which has a history of six hundred years and is installed on the south wall of the city hall. It is a beautiful and self-recognition clock. Every time there is punctuality, there will be a time for the sound, the saints appear, the rooster screams and so on. Surrounded by people, everyone is looking forward to seeing the moment when the small door opens. It is also a popular spot for wedding photos, and everyone wants to leave a lasting memory in romantic Prague. The entire square has fascinating beauty. Although tourists gather and make noise, it is so harmonious, like a miracle.
