This is interesting! Where is most of the best art located? I would love to research this more ... Do you know if the city ever cleans it up or do they leave it for people to enjoy?You would think that Athens- a city covered in graffiti would be the best place for street art in Greece but I was so surprised with how beautiful the street art is in Thessaloniki! I really admire the artists there, and I must visit again soon. Filia!
