In the early 1870s, Samuel Woller, the owner of a worsted wool spinning mill and weaving mill in Leśna, bought the Górne Młyny (Upper Mills) ground in Bolesławiec to construct a factory. The spinning mill, launched in 1873, was built and equipped according to English models; also raw materials (wool) were imported from England or its colonies. In the beginning, 150 people worked there. After the World War I, the factory was extended; in 1921, a building with a high tower with the inscription „Concordia” was erected, and the plant itself belonged to the fastest-growing companies in Bolesławiec. The spinning mill ceased production in 1943, and a plant producing aviation parts for „Weser – Flug AG” was opened in its premises. From 2 October 1944, the „Bunzlau II” forced labour camp was located on the 3rd and 5th floors of the „Concordia” factory building. The prisoners worked, among others, in the production of wings for the Focke-Wulf 190 fighter aircraft. The evacuation of the camp began on 11 February 1945. After the war, the buildings housed a branch of the „Hanka” knitting works from Legnica, and from 1990 – the „Sława” knitting works.
