Athletic Club, also commonly known as Athletic Bilbao (Basque: Bilboko Athletic Kluba), is a professional football club, based in Bilbao, Basque Country, Spain.
They are known as Los Leones (The Lions) because their stadium was built near a church called San Mamés (Saint Mammes). Mammes was a semi-legendary early Christian thrown to the lions by the Romans. Mammes pacified the lions and was later made a saint.
The club is one of three founding members of the Primera División that have never been relegated from the top division, the others being Real Madrid and Barcelona. Athletic have won La Liga on eight occasions, fourth most in the history of the league. In the table of Copa del Rey titles, Athletic is second only to Barcelona, having won it 24 times (per the team’s official records; the Royal Spanish Football Federation (RFEF) recognizes 23 victories). The club also has one of the most successful women’s teams in Spain.
