This 14th Century Gothic Castle was the home of Holy Roman Emperor Charles IV. It is located about 30 km (18 miles) from Prague, and makes a nice day trip for tourists staying in the city. The castle has served as a war fortress, a storehouse for treasure, and a royal home at different points. The building is designed with three terraced levels, each standing for different levels of importance. From lowest to highest, the sections are called the Imperial Palace, the Marian Tower, and the Big Tower. The Knights and the Emperor inhabited the imperial palace, the Marian Tower was reserved for the Empress, and the Big Tower was left for God, and has a chapel inside.
