Olsztyn Castle is a 14th-century brick fortress constructed by the Warmian Chapter to serve as an administrative and defensive stronghold. Situated in the heart of Olsztyn, Poland, the castle is a prominent example of Gothic defensive architecture, characterized by its massive walls, high tower, and strategic location overlooking the Łyna River.
The site is most historically significant for its association with the astronomer Nicolaus Copernicus, who resided here between 1516 and 1521 while serving as the administrator of the Warmian Chapter's estates. During his tenure, Copernicus managed the region's economy and conducted astronomical observations, including the creation of a unique astronomical table painted directly onto a castle wall.
