Just the walls remain of the 1815 Black Rock saw- and gristmill in Seneca Creek State Park. The structure was stabilized and representations of mill machinery were added in 1980.

The Black Rock Mill is just off the side of the Seneca Greenway and Seneca Ridge Trail within Seneca Creek State Park. The structure is a reminder of the work that was done in the area in the 1800s.

Built in 1815, little more than the walls remain of this saw and grist mill. Don't let that put you off though, peek inside you can find examples of mill machinery which were added in the 1980s to show how it used to work.
