The Baroque palace in Choroszcz was the summer residence of the noble Branicki family, and is now part of the Museum of Polish Interiors. As of December 2021, the town has a population of 5,960.[1]
In 1930, a psychiatric hospital was established in the town.[4]
Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was first occupied by the Soviet Union until 1941, and then by Germany until 1944. In 1940, the Russians closed the psychiatric hospital and deported some patients to the Soviet Union, while others were relocated to the local rectory.[4] In 1941, the Germans massacred several hundred remaining patients of the psychiatric hospital in today's Nowosiółki district as part of Aktion T4.[4]
In the 1921 census, 81.2% people declared Polish nationality, 16.2% declared Jewish nationality and 1.8% declared German nationality.[5] Choroszcz had 827 Jewish residents in 1897, and 450 in 1921. Nearly all were murdered in the Holocaust by the Germans during the Second World War.[citation needed]
