The prewar inmates were released by Polish administration already at the time of the invasion of Poland in the first days of September 1939 and the correctional centre stood empty.

[3] It was a main branch of several camps in Gmina Hańsk including Krychów, Hańsk-Dwór,[4] Osowa, and Ujazdów, for the innocuous captives expelled from the neighbouring settlements.

Due to proximity of the Sobibór extermination camp many of the Jews who dug the irrigation ditches in these camps were simply marched under the German guard for extermination by gassing at Sobibór,[4] along with the imprisoned Romani people.

[2] Krychów is located at the heart of Pojezierze Łęczyńsko-Włodawskie characterized by profusion of marshlands and meadows.

It is a legally protected area, a part of the Sobibór Landscape Park criss-crossed with hiking and biking trails for tourists.
