Built in 1889, the woolen mill is so well restored that its waterpower operating system is still working. In years past, the Mill transformed raw Willamette Valley wool into fabric and blanks which were werell known throughout the West. It is the only woolen mill museum west of Missouri.
The floor is supported by 48 12x16 inch beams, each 60 feet long. Guided tours are held on Tuesday through Sunday at 11 am, 1 and 3 pm. Self-guided tours can be conducted between 10 am and 4 pm.
The Mill is part of Salem's Mission Mill Museum, which also includes gardens and historic houses.
