Peavey–Haglin Experimental Concrete Grain Elevator

The Peavey–Haglin Experimental Concrete Grain Elevator is the world's first known cylindrical concrete grain elevator. It was built from 1899 to 1900 in St. Louis Park, Minnesota, United States, as an experiment to prove the design was viable. It was an improvement on wooden elevators that were continually at risk for catching fire or even exploding. Its cylindrical concrete design became the industry standard in the United States, revolutionizing grain storage practices. After its initial experiments, the Peavey–Haglin Elevator was never again used to store grain. Since the late 1960s it has been maintained on the grounds of the Nordic Ware company and is painted with their name and logo. The Peavey–Haglin Elevator was listed on the National Register of Historic Places in 1978, proclaimed a National Historic Landmark in 1981, and a Historic Civil Engineering Landmark in 1983.
