The Autódromo Juan y Oscar Gálvez is a race track, built on marshy land in the heart of Buenos Aires. The circuit was constructed in 1952 as a works project by Argentine President Juan Peron. The circuit is the only track to host the Argentine Grand Prix, which ran 20 times between 1953 and 1998.
The circuit is run clockwise, with several loops and extensions off of a rounded triangle. Since the track is built on reclaimed marshland, maintaining a smooth surface has been an issue, and the organizers did not seem to be interested in repaving the track each year.
The original course was Number 2. A simple lap around the triangle, with a very wide sweeping right hander, then after a short straight, a sharper right. A tight 180° led into a deviation along the back straight into the infield, and down to a wide 180° turn near the west entrance. All major races used this course until the 1960s.
When international racing returned to Argentina in the early 70s, it was originally on the new Number 9 circuit. The only changes were to shorten the leg out by the west entrance (which was now a wide spectator plaza) and tighten the left hander before the pits. This knocked more than half of a kilometer off of the lap distance.
The most recent circuit was a modified Number 6. Very similar to the early 70s Number 9, except for an irregular loop behind the pits. And the back straight loop used by all previous circuits had a new chicane at the exit, called the 'Senna S' (S de Senna).
