(JTA) — Four swastikas and “Hitler” were found on the former Mauthausen concentration camp.
The graffiti was written with a felt pen and carved onto walls at the former camp, the Upper Austria State Police said Monday in a statement, according to Austrian news reports. An investigation was launched into the incident at Mauthausen, which is now a memorial and museum.
The graffiti, about a half-inch high, was discovered in the former laundry and in the bunker area after visitors complained to a memorial employee on Sunday, according to the Austria Press Agency.
It is not known when the vandalism took place, though police reportedly suspect that it occurred the day before the discovery during public visiting hours.
