Bracia Łopieńscy is a company founded in 1862 in Warsaw by Jan Łopieński, specializing in the production of bronze, silver, and precious metal products. The company's headquarters were located at 55 Hoża Street. During the interwar period, Bracia Łopieńscy's products were considered some of the best on the Polish market, winning awards at national and international exhibitions, including in Paris, Lviv, and Poznań.
An important part of the company's activity was the production of sculptures, medals, and monuments. Among the designers for the company were Xawery Dunikowski, Cyprian Godebski, and Konstanty Laszczka. After World War II, the company focused on restoring destroyed monuments in Warsaw.
The company was reactivated in 1884 by Jan's sons, Grzegorz and Feliks, and in 1900, it moved to a new complex at Hoża Street. In 1950, it was nationalized, and after 1956, Tadeusz Łopieński opened a new studio that continues the business today. The company now operates under the name Pracownia Sztuki Dekoracyjnej d. Bracia Łopieńscy and is run by Anna Łopieńska-Lipczyk and her husband Wojciech Lipczyk.
