The Mill City Museum was opened in 2003 after it was built on the ruins of the Washburn A Mill, the flagship mill of  General Mills  (Washburn-Crosby Co. at the time) in 1880. the mill was revolutionary in that it was the most technologically-advanced mill at the time and it was also the largest. Minneapolis was known as the "Flour Milling Capital of the World", and the museum is dedicated to remembering that part of Minneapolis history.

There are several activities to take part in while you're at the museum in order to experience this history. Those activities include the Flour Tower elevator show, special exhibits that change a few times a year--and are free, and Water and Baking Labs if you're eager to learn more.

There is also the ruin courtyard which has the footprints of the (now gone) mill's machinery along the walls and ground, the rooftop observation desk from which you can gaze out upon the city, and a cafe called Bushel & Peck for when you're hungry and need something to eat.
