Hajnówka (Polish pronunciation: [xai̯'nufka]; Belarusian: Гайнаўка, Hajnaŭka; Podlachian: Hájnuvka; Yiddish: האַדזשנאָװקאַ, Hachnovka) is a town and a powiat seat in eastern Poland (Podlaskie Voivodeship) with 21,442 inhabitants (2014).Because of its nodal position, Hajnówka became a seat of two lumber-mills, wood spirit distillery and a major train station for 90 km (56 mi) of narrow gauge railways were built across the forest.After the war, some of them were rented by the Polish government under a contract to the British company The Century European Timber Corporation.However, in the late 1920s the contract was canceled and the wood processing plants came back under state control, while the Terbenthen factory was sold to a private owner.The initial conglomerate of wooden huts, barracks, tents and narrow, wood-paved streets turned into a town.The state financed construction of several hundred small houses for the workers and the town grew up rapidly.The factories were dismantled and sent to Russia while a large part of the inhabitants were in 1940 arrested by the NKVD and imprisoned in the Soviet Gulag system.All in all, until July 18, 1944, more than 700 inhabitants of Hajnówka lost their lives, the factories were robbed and then demolished, while the train station and parts of the town centre were levelled by aerial bombardment.Hajnówka has 8 schools as well as 5 churches (Catholic and Eastern Orthodox), 2 hospitals, a sewer system, a swimming pool and a museum.The main synagogue (there was still a small house of prayer) was built on a stone foundation around 1927/8 made of wooden logs.
