Old Town Square (Czech: Staromstsk &3; n MST &7;) is an ancient square in the old city of Prague, with a statue of Hus, a pioneer of religious reform, often known as Hus Square. Because it is Prague's most famous square, it is often called Prague Square. Cai Yilin's song of the same name is well known. The way to the Old Town Square is sure to be right if you look in the direction of the spires. Prague is known as the city of thousands of towers. The spires of churches, bell towers and other buildings point to the clouds. Turning around this building is the powder tower. Not long ago, we came to the Old Town Square. Hazy weather, people feel that it is still in line with the Prague temperament, a little melancholy, a little gloomy, full of philosophical thinking. This is from the east side of the square to the west. The southwest corner of the square is the world-famous city hall and astronomical bell tower. In the northwest corner is the new St. Nicholas Cathedral. The old St. Nicholas Cathedral is in the Castle District, west of the Charlie Bridge, and on the left bank of the Voltava River. The two churches look almost the same.
