Black Tower, Fortified tower at Prague Castle, Czech Republic
The Black Tower is a fortified structure within Prague Castle featuring thick stone walls and Romanesque architectural details. The structure originally served as the eastern gate to the castle complex and now houses an archaeological collection from the fortress.
The tower was built in 1135 as the eastern gate to the castle fortification and received its current name after a major fire in 1541 blackened its walls. During the reign of Charles IV in the 14th century, the structure was known as the Golden Tower because its roof was covered with gilded lead plates.
The walls contain inscriptions from the 16th century left by imprisoned debtors who were given certain privileges during their time here. These marks show how people experienced confinement within this structure.
The tower is accessible through designated pathways within the castle complex and can be explored as part of your castle visit. Plan to visit during the fortress opening hours and be aware that access may vary depending on current conditions.
The building was traditionally used as a prison for debtors whose daily lives unfolded within these walls. It is a lesser-known chapter in the castle's history showing how the tower served practical purposes across many centuries.
