The Litýš (German Litaisch, 435 m) is a Kegelberg (an old volcano) west of the significantly higher mountain Sedlo. There was a castle here that was built around 1422 by Siegmund von Wartenberg on Tetschen. This was intended to be used in the fight against the Hussites, as it was not far from the Kelchburg ruled by the Hussite leader Jan Žižka. Not much can be seen anymore, rocks functioned as castle walls, but they are said to have been important as counter-fortresses against Jan Žižka on the Chalice Castle.
