History

Dubuque in 1865, the shot tower can be seen on the far right edge.

The tower was built in 1856 to provide lead shot for the military. The invention of the shot tower enabled economical production of many nearly perfect lead spheres of the right size to fit in a musket. To make the shot, molten lead was poured through a grate at the top of the tower. The droplets that fell from the grate were of relatively uniform size, and the fall provided enough time for the liquid-metal droplet to form into a sphere before landing in the water below. The water cooled the lead to its solid state, retaining the spherical shape.

The shot tower struggled almost immediately due to economic downturn from the Panic of 1857. When the Civil War broke, the Union Army purchased shot from towers in St. Louis, Missouri. A St. Louis company, Chadbourne & Co., purchased the Dubuque tower, but did not use it. After the war, the Standard Lumber Company used it as a fire watchtower.

The tower was abandoned after a series of fires in 1911 destroyed the local lumber industry and damaged the tower’s wooden interior. The fire was determined to be arson, but no one was ever arrested. In 1976, the tower was listed in the National Register of Historic Places. Tuckpointing and repairs soon followed, and in 2004, the Shot Tower became part of ongoing riverfront renovations.
