Estadio San Mamés, AKA La Catedral (The Cathedral), is a football stadium in Bilbao, Basque Country, Spain. The stadium is 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 thrown to the lions by the Romans. The lions refused to eat Mammes and he was later made a saint.
It is currently building a new stadium, San Mamés Barria, which will open in 2013.
