The housing estate of Giszowiec in Katowice is workers’ colony, which is unique in Europe. It was built in the years 1906-1910 for the workers of the industrial plants – mostly of the mine "Giesche" (later "Wieczorek") owned by the Georg von Giesche's Erben company. The colony was designed by Emil and Georg Zillmann, who implemented the idea of a city-garden. The blocks of apartments and public buildings have been preserved to this day.
