In 1381, two castle structures existed, a new and old, which were both burned down by Lithuanian Duke Kęstutis.

[3] From a Teutonic scripture: "...castrum Osterode novum cum antiquoplene exustum est" – (the new castle in Ostróda together with the old one was completely burned down).

The access point from the east of the castle was by a bascule bridge, which led to a granite gate.

The village surrounding the castle served means for keeping storage, brewery and a forge.

During World War II the castle was burned down by the Wehrmacht Army.
