Karlštejn Castle was built by Bohemian King and Holy Roman Emperor Charles IV to house holy relics and the crowns of the kingdom and empire. Karlštejn Castle consists of three different levels, those being the Imperial Palace, the Marian Tower, and the Great Tower. Throughout the castle, Karlštejn housed many jewels and precious stones, symbols of royal authority and legitimate monarchy. Karlštejn Castle remains a cultural, historical, and architectural icon in central Europe and the Czech Republic.
Charles IV: King of Bohemia and the "Romans"
Charles IV’s efforts helped to elevate the city of Prague to new heights, establishing it as the intellectual and cultural center of Central Europe. Yet, his reign was marked by political disagreements and failures to centralize the government. One major, yet brief, threat to Charles IV’s authority came from Louis IV, the excommunicated emperor Charles IV replaced. Another major aspect of Charles IV’s authority was the elevation of Prague as a major player on the world stage for centuries to come.
