Diamond Silk Mill, historic mill in York County, Pennsylvania, U.S.
Diamond Silk Mill is a brick factory with three and a half stories in York, Pennsylvania, built around 1900. The building features a Romanesque Revival style with a distinctive octagonal smokestack, a hipped roof, and decorative corbelled brick cornice work that reflects its industrial past.
The mill was designed by architect John A. Dempwolf around 1900 and became a major employer in York's silk industry during the early 1900s. Decline began during the Great Depression and accelerated in the late 1930s when synthetic fibers replaced natural silk production.
The building sits at the corner of Ridge Avenue and Hay Street and is visible from the street. Access for touring and parking is limited since the historic structure occupies a tight urban location with few external facilities.
The building's smokestack rises 100 feet (30 meters) tall and served as a visual symbol of the facility's importance to local industry. Today, renovation has partly converted the building into residential units while preserving historic features like wooden ceilings and original window trim.
