We are dedicated to preserving the history of the county and fostering education on its relevance to the American experience. Our mission is to collect, preserve, exhibit, study, and interpret materials relating to the history and culture of Darke County, Ohio, as it represents a Crossroads of the American Experience. 

The DCHS operates the Garst Museum in Greenville, Ohio, and its 35,000-square-foot campus houses over 300,000 artifacts.
