Thats a rockin Castle
Now for people who arent Multi lingual let me put it in English a lil bit
Karlstein Castle differs entirely from other 14th century castles and also from the other founded by the same person. In Prague Charles IV built a family, royal and imperial residence based on the genius Ioci, Kasperk and Radyne as watch castles, Lauf at Nuremberg and Tangermunde in the center of the imperial feoffs and domains and other big and small castles as hunting seats or places to halt at on journeys.
At Karlstein, however, Charles IV fully developed in architectural forms the whole complicated system of his world outlooks and ideas on state, the ideology of the monarchal powers of the Czech king and his imperial dignity. His richly developed mystic thinking and feeling, his allegorical fantasy and the high demands he placed on culture predetermined the building programme of the castle. The foundation stone of Karlstein was laid in 1348 and the main building works lasted to 1356, the year of Charle's coronation as emperor. Charles Iv devoted care to the rich interior decoration of the castle until the time of his death on 1378.
