VIDEO: Tomb Of The Unknown Soldier of the American Revolution in PA Vandalized

The tomb of the unknown soldier of the American revolution in Philadelphia has been vandalized with graffiti that reads “Committed Genocide.”

CBS reports the National Park Service says it is working to remove graffiti on the Tomb of the Unknown Soldier of the American Revolution.

They’ve had to enlist the help of professional conservators to clean the monument in Washington Square because it is porous limestone.

Preservation at Work: The National Park Service is working to remove this graffiti on the Tomb of the Unknown Soldier of the American Revolution (at Washington Square) safely. We appreciate the offers to help that we’ve received, and we ask your patience while professional conservators continue this delicate task. Thank you for your encouragement and support.

The Problem: The wall of the monument is a very soft and porous limestone that’s susceptible to pitting and discoloration. To clean this stone without damaging it, we’ve tried non-abrasive steam cleaning and a gentle solvent. But, some paint on the wall remains.

The Solution: A professional stone conservator is now addressing this graffiti. The treatment saturates the painted stone with a mild solvent held in place by poultices (soft masses). After about two weeks, the stone’s appearance should improve.
