The city is located within the Capital District, which was planned in the form of a checkerboard anchored by Las Heras Avenue (from North to South), 25 de Mayo Av. (East to West), 9 de Julio Av. (east to west) and Guillermo Rawson Avenue (north to south). These four avenues form a perfect rectangle of 16 blocks in width (going from east to west and vice versa -horizontally-) by 10 blocks long (going up and down or North to South, and vice versa). This center of this rectangle is a square of 7 blocks in length by 6 blocks wide, delimited by Leandro N. Alem, Córdoba, Libertador San Martín and Rioja Avenues. This area is the city's downtown and, as such, is the most densely populated and concentrates most of the city's commercial, financial and institutional activities.
