The Cannelton Cotton Mill stands as one of Indiana’s most significant industrial landmarks and a powerful symbol of Perry County’s rich history. Built in the mid-19th century along the Ohio River, the mill played a vital role in the region’s economic growth and became nationally recognized for its advanced construction, innovative engineering, and high-quality textile production. Today, the preserved limestone structure remains a striking reminder of Cannelton’s industrial heritage and the people whose craftsmanship and labor helped shape the community, earning the site designation as a National Historic Landmark.
