Welcome to Marktown, Indiana. Marktown is on the National Register of Historic Places.

The town was created by Clayton Mark, owner of the Clayton Mark and Company that made steel pipes, to house employees. The town is bordered by a US Steel plant and the largest BP refinery in the world. The town is known as the only town in North America where residents drive on the sidewalks and walk in the street.

The ArcelorMittal Indiana Harbor steel mill in East Chicago, Indiana, is one of the largest integrated steelmaking facilities in the United States. The complex traces its origins to the Inland Steel Company, founded in 1893, and its massive brick headquarters—seen here—was built in the early 20th century to symbolize industrial power along Lake Michigan. Today, the plant remains a cornerstone of American steel production, encompassing multiple blast furnaces, coke batteries, and finishing lines. Now operated by Cleveland-Cliffs following its 2020 acquisition of ArcelorMittal USA, Indiana Harbor continues more than a century of continuous steelmaking on Chicago’s industrial lakeshore.
