Birthplace of the Star Spangled Banner, Keymar is home to Francis Scott Key. This original General Store, on old Key property that was built in the late 1800s, has been impeccably remodeled to allow you every comfort while being centrally located to historic Gettysburg, PA, Frederick, MD, the beautiful Catoctin Mountains, Mount Saint Mary’s University, Liberty Mountain Ski Resort, and so much more. Settle into history.
