Lukens National Historic District [PA]
The Lukens National Historic District chronicles the history of the iron and steel works industry in the town of Coatesville, Pennsylvania. The Lukens mill started as a small mill, but grew to become an industrial complex that held the world's largest plate mill. Today, the mill is open to visitors and stands much as it did when it finally closed down.
The historic district offers guided tours, a lecture program, house tours, and field trip programs. The website offers visitor information, a brief history of the Lukens mill, and an events calendar.
