The palace was first mentioned in the Zgorzelec city book in 1391, described as the property of the knightly von Grisslau (Gritzlau) family. From 1420, the settlement became the property of another family, the v. Hochberg, which had income here until 1454. After the transfer of Łomnica (German: Lomnitz) by King Władysław Jagiellończyk to the v. Gersdorff brothers, it developed significantly. This was expressed by the construction of a Renaissance manor house in the 16th century.
