Orgosolo has several (about 150) Murals and Graffitis painted on the walls of the houses and about every available spot in the city. The first Murals were signed Dioniso (an art collective) and date from 1969. Since then so many more pieces of art have been added. Worth a visit. Even Ché is present... :-) And after that enjoy a glass of wine from the Cantina Sociale di Orgosolo!!
