Graffiti Alley is known in Toronto for the beautiful artworks, creativity and vibrant colours. As one of the free galleries in Toronto, it's a city treasure and quite known to many locals, but to my knowledge, it's not quite described in pamphlets.
I can see why this might be the case though. For an alley that extends from Spadina to Portland on a street called Rush Lane, it's QUITE dirty on the side closer to Spadina. Although the side closer to Portland is also where people take out their trash, it's maintained a lot better than the side towards Spadina.
Graffiti Alley has many beautiful pieces, but there's many word related pieces and one small aspect of it is linked throughout the whole alley. Having visited a couple graffiti works in the world, I didn't think Toronto's Graffiti Alley was anything too special. However, if you're in the city and you want to pose in an art filled alley, Graffiti is the destination to visit!
