Dating from 1475, the Powder Tower was built as one of 13 gates to the city of Prague. The Powder Tower remained important to the Bohemian kings - until 1836, the Bohemian monarchs would pass through the Powder Tower on their way to St. Vitus Cathedral for their coronation.

The Powder Tower was designed by master builder Matěj Rejsek based on plans by Peter Parler for the Old Town Bridge Tower at the foot of Charles Bridge. It is now one of the few remnants of the fortifications that once surrounded the city.
