Kost Castle is one of the best-preserved Gothic castles in the Czech Republic, perched dramatically on a rocky spur where three picturesque valleys meet in the heart of Bohemian Paradise. With origins stretching back to the 14th century, this fortress has survived sieges, wars and centuries of neglect to stand proudly today as a living piece of medieval history. Whether you are a history lover or simply after a stunning walk through unspoiled nature, Kost will leave a lasting impression.

The castle rises above the confluence of the Svatoprokopské, Plakánek and Turnovské valleys, surrounded by sandstone rock formations, dense forests and tranquil fishponds. Two of the three original defensive ponds — the White and the Black — still exist today, reflecting the castle's towers in their calm waters. Spring brings lush greenery to the valleys, summer offers cool shade beneath the rocky cliffs, and autumn transforms the whole landscape into a canvas of warm colours.

• From Libošovice or Sobotka — a short scenic walk through the Plakánek valley, easy, approximately 20–30 minutes.
• By car — a road leads directly to the castle gate with parking available nearby.

• The castle is open to visitors from April to the end of October.
• There are four themed tour circuits: the Kinský family history, a torture chamber focused on criminal law from the 16th–18th centuries, a combined first and second circuit, and a shorter exterior-focused route.
• Kost has served as a filming location for numerous productions, including Terry Gilliam's 'The Brothers Grimm' (2005) and the TV series 'Knightfall'.

Legend has it that the great Hussite commander Jan Žižka himself tried to besiege Kost and, failing to take it, reportedly declared: 'This one is as tough as a bone' — and so, the story goes, the castle got its name. 'Kost' indeed means 'bone' in Czech.
