The Mill Ruins and the Flour That Built the City

Minneapolis exists because of a waterfall. St. Anthony Falls is the only major waterfall on the Mississippi River, and the energy it provided powered the flour mills that made Minneapolis the milling capital of the world by the 1880s — processing more wheat into flour than any city on Earth, producing the brands (Pillsbury, Gold Medal, Washburn-Crosby, which became General Mills) that American kitchens would stock for the next century.

The Mill City Museum at 704 South Second Street occupies the ruins of the Washburn A Mill, which was the largest flour mill in the world when it was built in 1880 and which exploded in 1878 (the previous building on the site), killing eighteen workers in a flour-dust explosion so powerful it was heard ten miles away. The museum is built into the remaining walls of the ruins, and the architecture — glass and steel inserted into limestone and brick — is a conversation between what was destroyed and what was preserved.

The exhibits trace the flour industry from wheat field to kitchen table, but the most affecting section is the Flour Tower — an eight-story elevator ride through the milling process, with each floor representing a stage of production and the stories of the workers who operated the machinery. The workers were largely Scandinavian immigrants, and their labor — twelve-hour shifts in dust-thick rooms where a spark could mean death — is told with the honesty the museum's industrial ruins demand.

The Stone Arch Bridge outside the museum crosses the Mississippi beside the falls and is the best place to see the Minneapolis that flour built: the ruins on the west bank, the modern city rising behind them, and the river that powered all of it running beneath your feet toward the Gulf of Mexico, 2,300 miles to the south.
