Tower in Prague, Czechia
This monumental entrance by which the coronation processions of Czech kings entered the Old Town is one of the most significant monuments of Late Gothic Prague. Completed in 1475, the Powder Tower, which formerly served as a gunpowder store, is still the starting point for the Coronation or Royal Route to Prague Castle. The viewing gallery is located at a height of 44 m.
