Mill City Museum - Higher 360 degree aerial panorama at the Mill City Museum. An alternate shot for my submission to World Wide Panorama: Museums, about 100' higher than the shot I used.
The Mill City Museum is built in the ruins of what was once the world’s largest flour mill. The museum focuses on the founding and growth of Minneapolis, especially flour milling and the other industries that used hydropower from the nearby Saint Anthony Falls on the Mississippi River.
The first Washburn A Mill was the largest flour mill in the world and contributed to the development of Minneapolis. On May 2, 1878, a spark ignited airborne flour dust creating an explosion that demolished the Washburn A and killed 18 workers instantly. The ensuing fire resulted in the deaths of four more people and destroyed five other mills.
Known as the Great Mill Disaster, the explosion served as a focal point for reforms in the milling industry to prevent the buildup of combustible flour dust.
