Organised naturism in Portugal existed from around 1920, but was suppressed until 25 April 1974. The FPN - “Federação Portuguesa de Naturismo” (Portuguese Naturist Federation) – was founded on 1 March 1977, at a meeting in Lisbon. The oldest and most representative club in the Portuguese Naturist Federation, is the Clube Naturista do Centro, founded on 20 November 1988.
