Like Karlstejn, this castle underwent a reconstruction overseen by Joseph Mocker. It started out as a hunting lodge, a weekend getaway for the Premyslid Princes and the seat of the royal master of hounds. Later, Wenceslas I built a stone castle on the spot and Charles IV used it in the 14th century.
The castle is over 900 years old.
Surrounding the castle are some hiking trails and a few shops and restaurants are located in the courtyard. You must take a tour to see the interior of the castle. Be wary of the midday break in the castle's opening times.
No direct/express route from Prague, apart from the occasional osobni (local) train. The best route is to head to Beroun from Praha Hlavni Nadrazi and change there.
Organised trips will get you there much quicker.
