Futbol Club Barcelona, also known as Barcelona and familiarly as Barça, is a professional football club, based in Barcelona, Catalonia, Spain. Founded in 1899 by a group of Swiss, English and Catalan footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Més que un club". Unlike many other football clubs, the supporters own and operate Barcelona. It is the second most valuable sports team in the world, worth $3.16 billion, and the world's second richest football club in terms of revenue, with an annual turnover of €560.8 million. The official Barcelona anthem is the "Cant del Barça", written by Jaume Picas and Josep Maria Espinàs.
