The south side of the National Theater was recently renovated and quickly thereafter vandalized once again. This side is the closest to the street and thus the least protected against various elements.
The whole building suffers deterioration because of its age and environmental factors like earthquakes and pigeon excrement but there is much more damage to the south wall because of humans.
People urinate on that wall, close to second avenue, and vandalize it frequently. It is subject to daily pollution. The cleaning of the building is needed to reduce the acidity from urine impacting the stones.
On May 2nd, someone drew graffiti on the wall in crayon. This was removed from the recently restored wall as carefully as possible with scalpel, eraser, soap and water but slight stains are still seen on the wall.
