Karlštejn Castle is a large Gothic castle founded in 1348 by Charles IV, Holy Roman Emperor and King of Bohemia. Located in the village of Karlštejn, the site was specifically designed to serve as a secure repository for the Imperial Regalia, the Bohemian Crown Jewels, and a vast collection of holy relics.
The castle is organized in a vertical hierarchy, with the most sacred and secure spaces located in the Great Tower at the highest point of the complex. While it underwent significant Renaissance and later Neo-Gothic modifications, the core structure remains a quintessential example of 14th-century defensive and palatial architecture in Central Europe.
Charles IV commissioned the castle to house his collection of holy relics and the Imperial Regalia. The construction was overseen by the architect Matthias of Arras and later by Peter Parler.
During the Hussite Wars, the Bohemian Crown Jewels were moved from the castle for safety, eventually ending up in the hands of Emperor Sigismund. The castle successfully withstood a seven-month siege by Hussite forces.
The castle underwent Renaissance-style modifications in the late 16th century. In the late 19th century, architect Josef Mocker led a controversial but extensive Neo-Gothic restoration to return the castle to its perceived medieval appearance.
Karlštejn stands as a primary symbol of the Czech statehood and the Golden Age of Bohemia under Charles IV. It represents the intersection of imperial power and religious devotion, serving as a physical manifestation of the 'Sacrum Imperium' concept where the monarch acted as the protector of Christendom's most sacred objects.
Scholarly debates and areas of uncertainty
The 19th-century restoration by Josef Mocker remains a subject of debate among architectural historians. Critics argue that the 'purification' of the castle removed authentic Renaissance layers, while proponents suggest it successfully preserved the structural integrity of the Gothic core.
