The history of the manor(Rittergut) begins in 1325 with the award of 400 Hufen of land to the knight Hans or Johannes Otatz in Gröben.

At that time the manor covered 800 hectares (1977 acres) and included a dairy and a distillery.

Soviet soldiers shot and killed the last owner of the manor, General Günther von Niebelschütz, on 26 January 1945.

Von Niebelschütz had married Antonie Tosca "Elisabeth" Hardt (1879–1946), daughter of Eduard Louis "Arthur" (1847–1934) and "Sophie" Therese Ulrike (1854–1941) (von Wallenberg) Hardt, in 1919.

The manor house (Schloß Schildeck) (Pałac, Gdańska 8, 14-106 Szyldak, Poland, 53°37′18.5″N 20°3′58.2″E / 53.621806°N 20.066167°E / 53.621806; 20.066167) was erected around 1910.
