San Mamés Stadium (also known as La Catedral, "The Cathedral"), was a football stadium in Bilbao, Biscay, Spain. The stadium was the home of Athletic Bilbao, known as Los Leones de San Mamés-Bilboko lehoiak (The Lions of San Mamés). They are known as Los Leones because their stadium was built near a church called San Mamés (Saint Mammes). Mammes was an early Christian, according to legend, who was thrown to the lions by the Romans. The club's new stadium, of the same name, was inaugurated on 16 September 2013.
