Peavey–Haglin Experimental Concrete Grain Elevator

The Peavey–Haglin Experimental Concrete Grain Elevator, built in 1899–1900, was the first circular concrete grain elevator in the United States, and possibly in the world. It is notable for proving the viability of concrete in grain elevator construction. Previous grain elevators, being built of wood, were expensive to build and vulnerable to fire. The elevator is located near the interchange of Highway 7 and Highway 100 in St. Louis Park, Minnesota. It was located along the Minneapolis and St. Louis Railway.
