The wall is legal for almost 10 years. It is located in the city center at the AKC Metelkova mesto, where is also a good youth hostel named Celica.
I recently visited Ljubljana and this wall. According to the staff at Celica, the wall is not legal and police comes by from time to time. The area is covered with graffs though.
People still graffiti here every day.
Is this wall still safe to paint?
