Preservation Maryland has been awarded $747,216 in funding from the National Park Service to preserve the historic Rock Run Mill, a contributing resource to the Lower Deer Creek Valley National Historic District, located within Susquehanna State Park in Havre De Grace, Maryland.

The Maryland Park Service (Maryland Department of Natural Resources) and Preservation Maryland will partner on the project; work will result in restoration of the roof, windows, doors, masonry, and structural components of the late 18th-century mill, as well as site work to protect the foundation from flood damage.

“Preservation Maryland is committed to revitalizing Maryland communities and preserving their unique history,” said Preservation Maryland President & CEO Nicholas Redding. “This grant, one of the largest received in the organization’s 90+-year history, allows us to preserve an early piece of our nation’s story. We’re thrilled to partner with the Maryland Park Service to preserve the structure as we commemorate the 250th anniversary of the United States in 2026.”
