Tomorrow, the Mill City Museum will open near the Stone Arch Bridge in Minneapolis, on the banks of the Mississippi. The museum will tell the story of how Minneapolis came to be the milling capital of the world in the 1880s. The museum is built in the old Washburn A mill, which was almost completely destroyed in a 1991 fire. The mill was once the most technologically advanced and the largest in the world. At peak production, it ground enough flour to make 12 million loaves of bread a day. Tom Meyer was one of the principle architects for the museum, and I met him in the museum courtyard. He says the 1991 fire first seemed like a huge setback to everyone trying to develop the old mill site.
