Built in 1850, the mill was named after Lewiston Mayor David Cowan and was originally used for grinding corn and flour. After 15 years, Cowan’s company purchased the building and used it to manufacture cotton and wool. By 1888, the mill employed 180 people and annually produced 300,000 yards of wool and cotton. In 1947, the mill became the Cotwool Mill, and continued manufacturing textiles until 1968. The building also housed the Sabelman Plastic Heel Co., which manufactured and shipped heels to shoe factories across the country.
