The Janesville Cotton Mill was built to serve as the workplace for the Janesville Cotton Manufacturing Company. The building was outfitted with the latest manufacturing technology in 1875. By 1880, The Cotton Mill employed about 250 people who were mostly women and first generation Irish and German immigrants. The Cotton Mill was used by various textile industries throughout the 20th century including the Janesville Shirt and Overall Company and the Janesville Apparel Company. Today, the three story building has been transformed into The Cotton Mill Apartments.
