The Old City Hall is on the Old Town Square, the most prominent place and the crowded place, because the most famous Prague astronomical clock is on this building. With more than 600 years of history, the appearance of the old city hall is also full of ancient traces. The ancient city has preserved the ancient buildings perfectly. If you want to overlook Prague's classic red roof, you can climb to the top of the old city hall tower. If it is sunset, the beauty in front of you should be shocking. Unfortunately, Prague has only a handful of sunny days throughout the year. I haven't met any of them. I hope I can enjoy them again next time.
