Argentine Senate, Senate chamber in Plaza del Congreso, Buenos Aires, Argentina
This upper chamber of the National Congress assembles 72 elected members from all provinces and the capital. The body meets in a neoclassical building on Plaza del Congreso, where senators debate legislation and vote on federal matters.
The chamber began operating in 1854 following the 1853 Constitution and initially chose senators through provincial legislatures. The shift to direct citizen elections in each province took place in 2001.
Each province sends three senators who speak for local concerns during floor debates and committee meetings. These voices reflect regional priorities and ensure that smaller territories carry the same weight as populous areas in the legislative process.
Sessions run from March through November, and visitors should check entry requirements in advance. Debates typically begin in the afternoon and may last several hours depending on the agenda.
The Vice President of Argentina presides over sessions but cannot vote except to break ties. This role connects the executive branch to the legislature and gives the office ceremonial importance during key votes.
