At the end of the 14th century, Teutonic Knights built a castle in Ryn, serving as a base for fighting with the Lithuanians. Until 1525, the castle was the seat of the commander. After two years of the construction of the castle, then the Grand Master of the Order Winrich von Kniprode arrived in Ryn to inspect and take over the castle, and returned to the Malbork by waterway. In 1723 Ryn received city rights granted by the Prussian King Frederick William I and in 1853 the castle was converted into a prison. Since July 2006, the castle operates as a hotel.
