Marine Mill is a historically significant gristmill located in Marine on Saint Croix, Minnesota. Built in 1839 by French Canadian immigrant Julius C. Burton, it was one of the first mills in the state and played a vital role in grinding grain for both local consumption and trade along the Saint Croix River. Its innovative limestone construction and wooden water wheels showcase cutting-edge engineering at the time. The mills skilled workers lived on site, forming a close-knit community that shared daily life together. Although operation ceased in 1875, Marine Mill has been preserved as a testament to Americas industrial heritage and is open for tours during summer months.
