The history of the Czchów Castle dates back to the 13th century, when a Romanesque watchtower was built here. In the 14th century, a defensive castle was added to the tower. It became the residence of the Czchów starostas, and was destroyed in the Swedish wars of the mid-17th century. Finally, the castle lost its military importance, and was turned into a prison, which was closed in 1772, after the first partition of Poland. Currently, the only remaining parts of the complex are a 14th-century tower and foundations of the defensive wall.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
