Cvilín Castle, Castle ruin in Pod Cvilínem, Czech Republic.

Cvilín Castle is a ruin located near Pod Cvilínem featuring stone remains that sit on elevated ground. The site shows typical medieval defensive design with preserved walls and structural elements still visible today.

Cvilín was first mentioned in 1238 as Lobenštejn; a stone castle replaced an earlier wooden one after the Tatar raid of 1241 and was rebuilt by 1250. In 1474 Matthias Corvinus damaged it during the Bohemian-Hungarian war, and George of Schellenburg restored it in the 16th century. After the Thirty Years' War it was abandoned, and in 1861 its masonry was taken for the road to Petrovice.

The ruins draw hikers and history enthusiasts who explore the remains and take in views across the surrounding landscape. The site has become a regular stop for people curious about how medieval communities lived in this region.

The route to the ruins follows marked hiking trails that start from the nearby village and are relatively straightforward to follow. Wear sturdy footwear as the ground is uneven, and the site remains accessible year-round.

The round tower stump in the southern courtyard measures 14 metres across, the largest such tower in the Czech part of Silesia. A well cut into the rock beside it was found by archaeologists in the 1930s. In 1861 much of the masonry was taken away to build the road to Petrovice.
