The Autódromo Juan y Oscar Gálvez is a motor racing circuit in Buenos Aires, Argentina built in 1952 under president Juan Perón, named Autódromo 17 de Octubre until Perón's overthrow, as 17 October was a date of great significance to his political party. The circuit is located in a park in the southern part of the city, and is situated on flat lands surrounded by large grandstands, giving most spectators an excellent view area of the whole circuit. Some races were run without the twisty infield section, reducing lap times significantly. The 1000 km Buenos Aires sports car event used the Autódromo as well as sections of highway situated near the track from 1954 to 1960. The 1000 km event would return again from 1970 to 1972, but using just the Autódromo section. The 20 Formula One Argentine Grand Prix races were held in the Autódromo between 1953 and 1998. The 10 Argentine motorcycle Grand Prix race were held in the Autódromo between 1961 and 1999.
