National Congress of Argentina

The National Congress of Argentina () is the legislative branch of the government of Argentina. Its composition is bicameral, constituted by a 72-seat Senate and a 257-seat Chamber of Deputies. The Senate, a third of whose members are elected to six-year renewable terms every two years, consists of three representatives from each province and the federal capital. The Chamber of Deputies, whose members are elected to four-year terms, is apportioned according to population, and renews their members by a half each two years.

The Congressional Palace is located in Buenos Aires, at the western end of Avenida de Mayo (at the other end of which is located the Casa Rosada). The ''Kilometre Zero'' for all Argentine National Highways is marked on a milestone at the Congressional Plaza, next to the building. Provided by Wikipedia
