Stadio San Mamés or San Mamés Stadion, or La Catedral is a football stadium located in Bilbao, País Vasco, Spain. San Mamés Stadion is the home of the La Liga club, Athletic Bilbao, known as "Los leones de San Mamés-Bilboko lehoiak" (San Mamés lions). They are known as Los leones because the 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 later he was made a saint.
The club's new stadium, San Mamés Barria, currently being built at a cost of 130 million euros and will be opened in 2013.
Opened in 1913, San Mamés Stadion is the oldest stadium in Spain (the oldest football field is El Molinón Stadium), together with the religious heritage has given it the nickname, La Catedral (Cathedral). San Mamés can be met almost 40 thousand spectators and is famous for the unique and boisterous atmosphere of the masses and devoted fans on match days.
Current stadium is almost entirely the same as the stadium that was used to hold the 1982 FIFA World Cup. In March 2006, a project was approved to replace San Mamés Stadion with a bigger stadium capacity 53,000 spectators. New San Mamés stadium will be built on the site of the former International Trade Exhibition Bilbao, adjacent to the current stadium. Construction started in April 2010 and completed the three-quarters that stadium, Athletic Bilbao will be moving to their new headquarters and original San Mamés will be demolished
