It was built by the Czech King and Roman Emperor Charles IV in 1348 as a place for safekeeping the royal treasures, particularly Emperor Charles IV’s collection of holy relics and the coronation jewels of the Holy Roman Empire. The fortress-like castle also served as the emperor’s summer retreat. Over 660 years old, Karlštejn Castle was never totally conquered. The castle even survived a 7-month siege  in the 15th century.
