Cisy Castle, Medieval castle ruins in Cieszów, Poland.
Cisy Castle is a medieval ruin on a hillside in the Czyżynki valley with preserved stone walls, a circular tower base, and a dry moat system. These remains show the layout of a border fortress from the 13th century.
Duke Bolko I had the fortress built in the 13th century to defend the borders of the Piast dukedoms of Świdnica and Jawor. Swedish forces destroyed it in 1634 during the Thirty Years War.
The castle demonstrates how medieval fortifications were integrated into the local landscape in this region. Local sandstone was used and the walls follow the natural slope of the hillside.
The ruins are accessible via marked hiking trails, including the Piast Castle Trail in the area. The site sits on hilly terrain, so proper hiking boots and adequate time for walking are recommended.
The moat remains dry and clearly shows the old defensive line that once surrounded the fortress. This makes it easy to understand the siege tactics that were used against such structures.
