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. History 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. Activities Ciudad hosts a large number of sports and activities, such as artistic gymnastics, artistic roller skating, basketball, basque pelota, cestoball, field hockey, football, golf, judo, karate, roller hockey, rugby union, rhythmic gymnastics, softball, swimming, synchronised swimming, taekwondo, tennis, volleyball, among others. Other recreational activities include latin and pop dance, pilates and yoga among others. Field hockey is the most representative sport of the club, with competitive teams in both men's and women's divisions. The hockey squads currently play at Metropolitano de Primera División, the top division of Argentine hockey league system. Although the institution had been founded in 1920, the rugby union team was not formed until 1938. The same year the team was affiliated to the Argentine Rugby Union, taking part in the "Competencia" tournament. The rugby union team is currently member of the Unión de Rugby de Buenos Aires (URBA) playing in Primera División B, the second division of Union's league system. In 1972 the team promoted to the second division, with 486 points scored and only 99 conceded. The top scorer was Emilio "Cachavacha" Aliaga, team's fullback. A years later Ciudad would be dissolved but was formed again in 1983, with some of the former 1972 players and many other from the youth categories taking part of the team. In 1986 the top division of Club Ciudad was the "Torneo de Ascenso" sub-champion. In 1994 the team was relegated to lower category but promoted in 1997 after a restructuring of the tournaments
