Mission Mill Museum, Textile manufacturing museum in Salem, United States

The Willamette Heritage Center is a museum on a five-acre site in Salem, Oregon. It brings together the Thomas Kay Woolen Mill, a two-storey brick building from 1896, with four relocated structures: the Jason Lee House and Methodist Parsonage of 1841, the John D. Boon House of 1847 and the Pleasant Grove (Condit) Church of 1858. Inside the mill, displays show original 19th- and 20th-century machinery and photographs of industrial wool processing.

The Thomas Kay Woolen Mill was founded in 1889 and became one of the region's major wool processing facilities. After it closed in 1962, the buildings were preserved as a museum to document the industrial history of the area.

The place shows how textile manufacturing shaped the everyday life and economy of this region. The preserved buildings and machines tell the story of the workers who labored here and built the industry.

Visitors should wear sturdy shoes since paths between buildings are often unpaved. The best time to visit is summer through early fall when the weather is pleasant and all areas are easily accessible.

The site also houses the Jason Lee House from 1841, one of the oldest wooden buildings in the region. The parsonage structure reflects the early Methodist settlement of the Northwest.
