Radzyń Chełmiński Castle

Radzyń Chełmiński Castle is a historic Brick Gothic fortress located in the town of Radzyń Chełmiński within the Kuyavian-Pomeranian Voivodeship of Poland. Situated near Castle Lake, this monumental structure was originally established as a wooden fort in 1234 by Hermann von Balk for the Teutonic Knights. Following destruction during local uprisings, it was reconstructed in brick between 1270 and 1285, before being rebuilt into its current grand form from 1310 to 1330. As one of the oldest castles built by the Order, it served as a vital Commandry seat and witnessed significant military history, including capture by Polish forces after the Battle of Grunwald in 1410 and later involvement in the Thirteen Years' War.

The castle's decline began in the 17th century when it suffered severe devastation during wars with Sweden, eventually falling into ruin. After the First Partition of Poland in 1772, Prussian authorities ordered its deconstruction, repurposing much of its brickwork for local housing until the demolition was halted in 1837. Despite losing its eastern extensions, moat, and southern buildings, the site survived both World Wars. A major restoration project undertaken between 1961 and 1968 cleared debris, restored the main wall to its original height, and replaced the chapel roof. Today, the ruins remain a protected historical site where visitors can explore the preserved inner keep, cellars, courtyard, and the restored southern facade, offering a tangible connection to medieval Teutonic architecture.
