Several monuments on the Gettysburg Battlefield were recently defaced with oil, resulting in costly damage, according to park officials. In a release issued Friday, Jan. 9, 2025, the National Park Service at the Gettysburg National Military Park shared that several monuments on the Gettysburg battlefield had been "defaced with oil-based substances." "While possibly intended as symbolic or ritualistic, the damage is real and lasting," the release stated, adding that "porous stone absorbs oil deeply, making stains nearly impossible to remove."
