The mannor from early 18th. century was errected as a residence of the owners of Belchatow, Stanislaw and Franciszek Rychlowski. The late barock building was surrounded by a park. Next owners, family Kaczkowski, rebuilt it and enlarged. Kaczkowski was very modern and good manager of the town. He errected many social buildings, sponsored schol etc. He also allowed Jewish emigrants from Prussia to settle down, what in the final helped to establish a weaving industry and brought the prosperity to town. The mannor (or palace) was bought 1943 by Dr Waclaw Olszewski.
