Houska Castle was built by the noble family of Dubá. Sometime around 1590 it was rebuilt in the Renaissance style. The robust structure has a rectangular ground plan, with a closed central yard, and still has the original Gothic windows. The roof is completed with a little lookout tower. The chapel offers unique wall paintings from the 14th and 16th centuries. Other attractions are the Zelená Světnice (Green Room), decorated with paintings from the 16th century, and the knights' lounge. Houska Castle is one of the best-preserved royal castles from the period of King Přemysl Otakar II. Legend has it that the chapel is seated just above the gate to the hell.

On weekdays, beyond the main tourist season, visitors may look into the newly installed Limbo! During summer, Houska Castle regularly comes to life through cultural events - traditional fairs, fencers, old crafts, musicians and singers, etc.
