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.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
