Walls in primary school courtyard

Legal graffiti wall in Bolzano, Italy


There is 50m stretch of walls inside the school courtyard that are legal to paint. Really good opportunity for flix with mountains in the background.

Streetview from Jun 2014 still shows it. It's on the basketball field. Also seen on google earth: goo.gl/5EG8dS

I painted here time like 3 months ago, and is still used, nobody says/d nothing

Is this wall still safe to paint?
