The very first mural, called Murales, was drawn in Orgosolo in 1968 by the Milanese anarchist group Dioniso. After seeing the film Banditi a Orgosolo, the drawing teacher Francesco del Casino from Siena, who was close to the Italian Communist Party, settled in Orgosolo and began painting pictures on the walls of houses in Orgosolo with students in 1975. The occasion was the 30th anniversary of the partisan struggle against fascism. The paintings began in Sardinia in the rather unknown village of San Sperate. The murals in Orgosolo initially expressed protest against the planned NATO military training area on the Pratobello. The protest is also directed against the Milanese company bosses who embezzled funds from the development plan for Sardinia. More recent portraits comment on e.g. B. world politics - Helmut Schmidt is called an “expert in state murder” because of Stammheim, a victory by Cambodian and Vietnamese fighters against the USA on April 25, 1978 is celebrated and the number of innocent victims for the overthrow of Saddam Hussein is questioned. Other images depict simple shepherd and village life, advocate for the preservation of the Sardinian language or even contain advertising messages. An ironic Murales also makes fun of Alfredo Niceforo's studies of crime in Sardinia (see story). Many of the approximately 120 murals are stylistically based on cubism in the style of Picasso's Guernica, but there are also more realistic paintings among them. In addition to Francesco del Casino, the artist and self-taught artist Pasquale Buesca, who also lives in Orgosolo, the artist group “Le Api” and the Milanese artist Massimo Cantoni were responsible for the murals. Despite some damage, for example due to house renovations or weather, all of the murals are largely very well preserved.
