The Powder Tower (Prašná brána) is without doubt one of the most beautiful and famous buildings in Prague and is a symbol of the city. In the past the tower was a part of the Old Town’s fortification system, and coronation ceremonies passed through it. Thanks to its very strong foundations, the Powder Tower has lasted through the centuries; the monument and the Old Town Bridge Tower are the only other survivors of the original Old Town fortifications.
When the centre of Prague was extended to New Town, the Powder Tower became neglected. The town councillors then decided to rebuild the almost completely dilapidated building, because in such a state it was not a true symbol of the Old Town.
Reconstruction of the building began in 1475 and was carried out by Matyáš Rejsek of Prostějov; the structure, including the roof, was over 42 metres high. In the end the Powder Tower became redundant, and some people were of the opinion that it should be pulled down.
From the middle of the 18th century, the Powder Tower was used to store gunpowder, and it was during this period that it acquired its current name. During the Prussian siege of Prague the building was again almost destroyed, then in the 19th century it was restored to its former glory by architect Josef Mocker.
Today the Powder Tower is 65 metres high, and is open to the public. From its 44-metre high gallery you can enjoy enchanting views over the City.
It is located on the boundary of Na Příkopě street and Náměstí Republiky.
