The Powder Tower, which by the way is near the Town Hall of Prague, is 65 meters high. But when it was established, it was called the "New Tower." The reason is that it was then new in relation to the bridge tower of the Old City, which was built about a hundred years before it.
The name of the tower was replaced in the 17th century to the name "Powder Tower " because gun ammunition used to be stored here.
Today the tower is open to visitors. Those interested can see it at the exhibition, where you can learn about the history of this impressive building.
