[1] Ryn Castle is a late fortress built by the Teutonic Order.

[2] The fortress was built in the place of a former, smaller stronghold, as ordered by the Grand Master of the Teutonic Order Winrich von Kniprode in c. 1377, to serve as a convent and a headquarters for launching attacks against the Grand Duchy of Lithuania to its east.

In 1410, after the Teutonic defeat at the Battle of Grunwald, the castle's fortifications were dismantled, limited to one Gothic building in the eastern part of the castle-complex.

At the onset of the Thirteen Years' War, in 1455, the castle was occupied by local peasants, later recovered by George von Schlieben, whom massacred the peasants in front of the castle at the Battle of Ryn.

After 1945, the castle was adapted to serve as a community centre, a small museum and the municipal council.
