The tower was built in 1856 to provide lead shot for the military. The concept of a shot tower solved the problem of how to produce many cheap, nearly perfect lead spheres of the right size to fit in a musket. To make lead shot, molten lead was poured into the top of the tower, where it passed through a grate. 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.
