Castle Kętrzyn is a 14th-century Teutonic fortress located in the Masurian Lake District of Poland. Originally constructed by the Teutonic Order, the castle was rebuilt and expanded over several centuries following repeated fires. It currently houses the Wojciech Kętrzyński Museum, which focuses on the regional history and ethnography of Masuria. The structure features a distinctive Gothic tower and a reconstructed defensive wall segment. Visitors can explore permanent exhibitions detailing the medieval era, local folklore, and the 20th-century transformations of the town. The castle serves as the primary cultural institution for the municipality of Kętrzyn.
