Greenbank Mill Associates, Inc. is a not-for-profit organization dedicated to preserving the Greenbank Mill National Historical District as a public museum, and expanding public knowledge of Red Clay Valley industrial, agricultural, and social history through on-site educational and recreational programming.

Come See Our Garden

Greenbank Mill is home to lovely herb and vegetable gardens. The produce from our gardens is used for dyeing fabrics with period correct dye stuffs, food preparation, etc. Our gardens are open for viewing during regular visiting hours. We also offer dyeing workshops with natural herbs. Volunteers welcome!

Be part of our barn restoration project! Our barn reflects the seasonal changes of an early 19th century barn and currently houses heritage livestock in the form of merino and Leicester Longwool sheep. Accompanied by a miller's house, the barn is a wonderfully interactive museum space

   How Can I Help?

One of the most frequent questions we hear is “How can I help?” The answer is to volunteer in any one of many capacities. The key to Greenbank Mill Associates’ success during the last 20 years has been its volunteers. They stepped forward and preserved the mill, raised money, and even helped do restoration work. As Greenbank grew, so did the role of volunteers in areas such as publicity, archaeology, grounds and building maintenance, livestock, and many others.

Greenbank has continued to grow and so have our volunteer needs. To learn more about our volunteer opportunities, complete our application below and email to
