Czachówki [t͡ʂaˈxufki] is a village in the administrative district of Gmina Biskupiec, within Nowe Miasto County, Warmian-Masurian Voivodeship, in northern Poland.

The estate consisted of a central building with about 680 hectares (1,700 acres) farmland and numerous additional farms.

Grandson Georg Konrad Lebrecht Rüchardt, who had not inherited the estate, had gone to Moscow in about 1880 and married into the trading company Wogau & Co, where he became a director and co-owner.

Some of the family managed to escape to the west; others were called into the war or captured and brought to the Russian Gulag.

The Schackenhof attached farms were demolished and all the agricultural land and meaningful buildings were integrated into the government-run LPG.
