Helenów Park, formerly known as January 19th Park, is a historic 12-hectare park in Łódź, located between Północna, Źródłowa, and Smugowa streets. Its origins date back to 1867, when Karol Anstadt established a brewery on the Łódka River. Soon after, the Anstadt family began developing the area, which led to the creation of the park, opened to the public on January 26, 1885. Designed by the Berlin-based company L. Späth, the park became an elegant recreational space, featuring ponds, fountains, rose alleys, and a zoo where exotic animals could be admired. During its heyday, from 1885 to 1914, Helenów attracted wealthy residents of Łódź and hosted various cultural events, concerts, and hot air balloon shows. Interestingly, in 1890, the park hosted "Olympic Games," and in 1896, it saw the first film screenings in Łódź. After World War I, the park was devastated, and attempts to restore it after World War II, when it was given a new name, did not bring the expected results. In 1994, its original name was reinstated, and in the 21st century, a revitalization process began. The park gained new attractions, including floating fountains with light effects. Today, it serves as a place of relaxation and recreation, with several of its trees recognized as natural monuments. Helenów Park has been entered into the register of historical monuments, and its rich history and architecture continue to attract both residents and tourists.
