The grain silo was built between 1899 and 1900. It still stands today. The symbol advertises Nordic Ware , the current owner of the building.

The Peavey-Haglin Experimental Concrete Grain Elevator is a 1899-1900 erected round silo of concrete for the storage of grain and was the first structure of its kind in the United States and possibly the world. It is noteworthy for showing the potential for concrete to be used in the construction of grain silos. Previously, these were made of wood and were therefore expensive and prone to fire. It stands in St. Louis Park near the intersection of Minnesota State Route 7 and Minnesota State Route 100 on a previous line on the Minneapolis and St. Louis Railway .

The structure was commissioned by Frank Peavey, the owner of a large grain trading company, and designed and built by the engineer Charles F. Haglin from Minneapolis . He also built the Minneapolis City Hall , the Grain Exchange Building, the Pillsbury Building and the Radisson Hotel as a contractor. The silo was built by pouring concrete into wooden molds that were held together by steel hoops. The engineers were hesitant at first, not knowing how much pressure the structure could withstand, so they limited the height to 68  feet , about 20.7 m. After a stress test that involved filling and emptying the silo, the structure was raised to its current height of 125 feet (about 38 m). The inside diameter is 20 feet (6.1 m) and the wall thickness is 12  inches (30.5 cm) near the foundation and decreases to 8 inches (20.3 cm) to the top.

Although the load test was successful, the silo was never filled again, but its design paved the way for many other grain silos of this type across the United States.

Because the structure is noteworthy, it was entered on the National Register of Historic Places on December 19, 1978 , declared a National Historic Landmark on December 21, 1981 , and added to the List of Historic Civil Engineering Landmarks by the American Society of Civil Engineers in 1983 .
