Minnesota's front-and-center role in food history might have been a mere footnote if it weren't for St. Anthony Falls. This 16-foot precipice, the only falls along the Mississippi River's 2,340 miles, provided the energy in the pre-electricity era to run the mills that spawned General Mills, Pillsbury and a host of other food giants.
The falls were named in 1680 by Father Louis Hennepin, a Franciscan priest who christened them for his patron saint, Anthony of Padua.
The falls' power was first harnessed in 1823 by soldiers from nearby Fort Snelling, who built a crude grist mill on the river's West Bank.
The first flour mill appeared on the East Bank in 1854, and as technological improvements revolutionized the milling process over the next few decades, the area around the falls — sacred to Native Americans — became crowded with several dozen mills, all using the river's water power via an intricate network of dams and canals to churn out flour on a monumental scale.
The falls were also the site of the nation's first urban hydroelectric power plant.
At their peak in 1916, the city's mills were producing 3.6 billion pounds of flour a year, enough to fill the Metrodome 1 ¼ times.
By 1930, the city lost its "Flour Milling Capital of the World" title to Buffalo, N.Y., and the falls' last water-powered mill was shut down in 1960.
Remnants of the district's powerful industrial past remain. The Pillsbury A Mill, the world's largest and most advanced flour-making operation when it opened in 1881, still stands at 301 SE. Main St. At its peak, it produced 3.5 million pounds of flour a day.
