The Durable Slate Company, Columbus, Ohio, restores historical Steeple Square in Dubuque, Iowa. Built between 1864 and 1867, St. Mary’s Catholic Church in Dubuque, Iowa, served as an economic, social and educational center for German-immigrant parishioners. For almost 150 years, the church was a central meeting space for working-class citizens. It was a gateway for newcomers to Dubuque, hub for downtown neighborhoods and source of community pride.
