Shields Woolen Mill is located along the edge of the Mississippi River in Davenport, Iowa, United States.

Because the Civil War cut off cotton supplies from the southern states, wool increased in popularity in the North.

By 1870 he employed 52 people and the annual production value of the mill was $36,000, which made it the sixth largest industry in Davenport.

In the 1890s the mill employed 140 people and its product line included clothing, cashmere, flannels, and blankets.

It is constructed in brick with a stone foundation and basement, which is exposed on the south elevation of the building.
