Prague Castle, with its origins dating back to the 9th century, stands as a testament to the rich history of Prague and the Czech Republic. Founded around 880 by Prince Bořivoj of the Premyslid Dynasty, the castle has been a central seat of power for kings of Bohemia, Holy Roman emperors, and presidents of Czechoslovakia. The complex, noted for its architectural evolution from Gothic to Baroque styles, is also home to the Bohemian Crown Jewels and has been recognized as the largest ancient castle in the world by the Guinness Book of Records.
