Pražský hrad

Prague Castle (Czech: Pražský hrad; [ˈpraʃskiː ˈɦrat]) is a castle complex in Prague, Czech Republic serving as the official residence and workplace of the president of the Czech Republic. Built in the 9th century, the castle has long served as the seat of power for kings of Bohemia, Holy Roman emperors, and presidents of Czechoslovakia. As such, the term "Prague Castle" or simply "Hrad" ("the Castle") are often used as metonymy for the president and his staff and advisors. The Bohemian Crown Jewels are kept within a hidden room inside it.

The castle is the most visited tourist attraction in the Czech Republic. In 2024, the castle attracted 2.59 million visitors.
