The term "Mill Complex" typically refers to a group of interconnected buildings and structures used for industrial milling processes. These complexes often include facilities for grinding grains, processing raw materials, and producing finished products. They played a significant role in the development of industries during the Industrial Revolution. Mill complexes can vary in size and design, often featuring large machinery and storage areas. Many historical mill complexes, such as those found in New England or along rivers, have been preserved as cultural heritage sites, showcasing the evolution of milling technology and its impact on local economies.
