A total testament to the genius that was Otto Gehlig! The architect and builder constructed this house in 1882 for Juliusz Heinzl, who would go on to become his father-in-law. Heinzel founded his own weaving mill in 1864 at this site, which did so well that it became the largest production complex for wool goods in the entire kingdom of Poland at the time, leading Heinzl to get the moniker: “King of Wool.” 
Naturally, he needed a house fit for a king, and Gehlig delivered. This house (also referred to as a palace) has three sections: a middle section where the residence was, and two connected side buildings. It also has gorgeous bay windows, and it’s topped with a statue of industry and commerce. 
Now, this spot is a historical monument and full of offices. It’s the site of Łódź’s City Hall and the Provincial Government, so you’re able to go inside and check it out! 
But even if you don’t want to go in, it’s worth walking by – especially at 12 p.m. Since 1998, the official bugle call of Łódź, Prząśniczka, has been played at the building at noon every day from the window of the City Council office. The song, which was composed by Stanisław Moniuszko, means “the spinner” and refers to the city’s industrial heritage.
