The world's largest medieval castle is the Malbork Castle in Poland.

This castle, built by the Teutonic Knights in the 13th century, spans over 5 miles in length and covers an area of 250 acres. It was constructed between 1274 and 1309 and took nearly 100 years to complete. The castle's sheer size and impressive architecture earned it a UNESCO World Heritage Site designation in 1997.
