This wall is still in use and gradually evolves. Got its name from the famous artists that used to work here in the past - above all its founder Sting Ray. If you're a fan of street art, you should not miss it. And if you're a street artist, maybe you can add up some of your work to the gallery. Also, since you're in the neighbourhood, you can visit The Global Angel Wings Project which is another interesting graffiti located nearby.
