Kost is considered to be one of the most important and well-preserved Gothic castles in the Czech Republic.
While most castles are situated on a hill, Kost instead nestles on a sandstone point where three massive rocky valleys meet about 18 kilometres from Jičín.
A well-known legend states that Kost got its name in the era of siege by Jan Žižka, who after an unsuccessful time besieging said that the castle is as tough as a bone (kost) and thus belongs to a dog. Guided tours will take visitors to the castle’s aristocratic chambers, armoury and St. Anne’s chapel. Histories of the Kinsky family and punishments set out by the law at the time are described in the torture chamber.
