The writers of Malmø, Sweden got a new legal wall this weekend when the city of Malmø decided to give them a 90 meter long fence at Parkgatan to paint on legally. City officials noted that their experience from the P-Huset Anna legal area in Central Malmø was that legal walls were very popular and that illegal graffiti didn’t spread from them! Go Malmø, now you have twice as many official legal areas for graffiti compared to big brother Copenhagen.
Two articles in Swedish here and here.
