Dec. 31 marks not only the end of the year, but also the end of an era.

Steelmaking operations at U.S. Steel’s Hamilton Works officially close for good on Tuesday, after the Pittsburgh-based corporation announced in October that production would not resume at the bayfront mills.

Though it didn't axe coke-making activities, the decision represents the culmination of more than a century of steelmaking at the site. 

For decades, even as it changed names, the once-bustling complex was a Steeltown icon, employing thousands in the city and producing materials that helped propel North America’s industrial rise.

CBC Hamilton has compiled pictures that were taken at the works — Stelco, as many will prefer to remember it — over the years.
