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 subcamp (a branch of the Gross-Rosen concentration 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.
