Arcigay
Arcigay is Italy's first and largest national gay organization.
The association was first founded as a local association in Palermo in 1980, then nationally established in Bologna in 1985. The organisation became known throughout Italy for its campaign for civil unions. The President of Arcigay is Paolo Patanè, its honorary president, who helped found the organization, is Franco Grillini.
Arcigay has often protested against the Vatican's opposition to homosexuality and LGBT rights.
Many Italian gay venues require their patrons, both native and foreign, to purchase Arcigay membership, in addition to the admission cost, even those who are just visiting the country for a short time.
