Plainfield Woolen Company Mill

The Plainfield Woolen Company Mill is a historic mill building on Main Street in Plainfield, Connecticut. It is a large brick building, four stories in height, located between Main Street and the Moosup River. Built in 1901, the building played a vital role in revitalizing the local economy, which was stagnating at the time. It remained the site of active textile manufacturing until 1984. The building is a visually distinctive landmark in the community, in part because of its unusual monitor roof.

The building was listed on the National Register of Historic Places in 1985. The building was renovated and converted into condominia.
