Kost Castle in Bohemian Paradise

Deep in the heart of the Bohemian Paradise (Český ráj), roughly 18 km from the town of Jičín, stands one of the most impressive architectural treasures in the Czech Republic. Kost Castle remains a rare survivor of the medieval age, remarkably well-preserved and steeped in local lore. Its name—which translates to “Bone”—is said to come from the legend that the fortress was as hard as a bone, rendering it impossible to conquer for centuries.

A Legacy Preserved: Ownership and History

Today, the castle is owned by the noble Kinský family, specifically brothers Giovanni and Pio Kinský dal Borgo. While they reside primarily in Italy, their connection to the estate remains strong, with the company Kinský dal Borgo overseeing the meticulous management of their Czech assets, including the nearby Karlova Koruna Castle.

Following a massive, multi-year reconstruction project completed in 2021, the castle is in better shape than ever. This initiative, which focused on stabilizing the subsoil and repairing historic walls, led to fascinating archaeological discoveries. Experts now believe the castle was built approximately 100 years earlier than previously recorded, and a previously unknown secret passage was unearthed, adding to the site’s enduring mystery.

Exploring the Castle Circuits

Visitors in 2026 can choose from four distinct tour circuits. Each offers a unique perspective on the history, architecture, and darker legends of this Bohemian landmark.

Circuit I: Castle Palaces

This tour invites you to step into the lives of the Kinský family. You will explore the historic palace interiors, walk through the armory filled with antique rifles and pistols, and visit the chapel and the authentic black kitchen.

Circuit II: The Medieval Torture Chamber

For those interested in the grittier side of history, this circuit dives into the realities of medieval criminal law. You will encounter a working guillotine, a witch’s cage, and other implements of justice. This route also includes access to the ground floor of the Great White Tower, where a modern exhibition features animations and models explaining the castle’s construction.

Circuit III: The Complete Experience

If you have the time, we recommend the combined circuit. It covers the entire castle complex, including all courtyards, the salla terena, the chapel of St. Anne, and the torture chamber. Please note that this is an extensive tour and may be challenging for small children.
