The MIO Ice Cream Factory in Chênée, a district of Liège, traces its origins back to the end of the 19th century. Around 1898, the Italian immigrant Antoine Marzale began selling ice cream in the streets of Liège. What started as a small street business gradually developed into a regional ice cream producer operating under the name MIO.

As demand grew, a production facility was established on Rue des Grands-Prés in Chênée. In this factory, different types of ice cream were produced, including traditional dairy ice cream, ice cream bars, and products coated with chocolate. The products were distributed mainly in the Liège region and other parts of Belgium.

After nearly a century as a family-run business, the company was sold in 1992. Production at the original site gradually declined in the following years. Around 2006, the factory in Chênée was permanently closed. The MIO brand itself continued to exist and was later produced by the Belgian ice cream manufacturer IJsboerke.

After the closure, the factory site remained abandoned for several years before the buildings eventually disappeared, marking the end of a small but notable chapter in the industrial history of the Liège region.
