Gunpowder Tower is located in the old city of Prague. Its black Gothic spire is 65 meters high and is one of the landmarks of Prague. The gunpowder tower was once one of the earliest 13 gates in Prague's old city. It was rebuilt on the site of the gate in the 15th century. It is still the starting point of the road to the coronation of the castle. Background: In the 16th century, the king allowed magicians to study alchemy in the powder tower. In the 17th century, it was used as a powder depot, hence the name of the powder tower. The back of the tower is more beautiful than the front. There is a square in front of the tower. Some folk artists perform. I see an artist who plays with bubbles. Bubbles are colorful in the sunshine and attract a lot of people.
