Biedrzychowice [bjɛdʐɨxɔˈvit͡sɛ] is a village in the administrative district of Gmina Olszyna, within Lubań County, Lower Silesian Voivodeship, in south-western Poland.

Building was begun by order of the first owner, Konrad von Nostitz, in 1527, and was completed in 1580.

It was renovated by Moritz Christian von Schweinitz in 1702 in the baroque architecture style.

It stayed in the hands of von Pfeil family until the end of World War II.

It was then used as an office of the Państwowe Gospodarstwo Rolne farm authority, and in 1960 was converted to an educational institute.
