A day at the mills, Paterson Great Falls National Hisorical Park, 2016.

Date unknown. Paterson's success was built largely on the innovative, entrepreneurial, hard-working spirit of its citizens - most of whom were immigrants. In the late 19th and early 20th centuries, many worked in mills manufacturing everything from cotton textiles, steam locomotives, Colt revolvers and aircraft engines to silk fabrics in such quantities that Paterson was known as 'Silk City'. Former mill buildings includ the Rogers Locomotive Building (Paterson Museum), the Colt Gun Mill ruins and the Allied Textile Printing (ATP) site ruins. All are located within the National Historic Landmark district.
