Founded in 1989, the Central Maryland Heritage League is a nonprofit organization created to promote the cultural, historical, and natural heritage of the Middletown Valley. C MHL advocates, encourages, and enhances public awareness of this heritage through the conservation, interpretation, preservation and stewardship of the resources contributing to the South Mountain State Battlefield and its surrounds — including Wise's Field, historic Dahlgren Chapel, and the Dahlgren family involvement in the events relating to the Civil War in Maryland. While the South Mountain State Battlefield is one of our prime initiatives, we have acquired Dahlgren Chapel, the private family chapel of Madeleine Vinton Dahlgren, built in 1881 atop South Mountain. We are the stewards of Dr. Austin A. Lamar's Surgical Suite and Medical Museum, located in downtown historical Middletown, Maryland. We also hold easements on several properties.
