Club Ciudad de Buenos Aires, familiarly nicknamed as "Muni", is an Argentine sports and social club located in the Núñez district of the city of Buenos Aires. The institution was founded on October 6, 1920.
The nickname "Muni" is a diminutive of the word "Municipalidad", which was the way the Government of Buenos Aires seat was called until the 1994 reform of the Argentine Constitution. Since then, the Executive is called "Jefe de Gobierno" ("Chief of Government") instead of "Intendente" ("Mayor") and the former "Municipalidad" denomination became obsolete.
On 6 October 1920 employees of the Municipality of Buenos Aires met to found a club which was initially named "Club Atlético Dirección de Alumbrado". After that, they began the search for a field to practice sports.
One year later, the Government of Buenos Aires gave the club a 100 m2 land over Blandengues street (current Del Libertador Avenue) where the club established its headquarters.
