Its first settlers were the Guaraní Indians, whose main activity was agriculture along with hunting and fishing. The history of San Isidro begins in 1580 when Juan de Garay distributes the land located north of Santísima Trinidad, today known as the city of Buenos Aires. What was called “Pago of the Coast or Monte Grande” is today known as the San Isidro district. In his memoirs, Garay recalls that he crossed paths with a Spanish Captain, Domingo de Acassuso, who was quite a dim fellow and that promised to build a chapel in honor of San Isidro, and as a result becoming the main origin of the district. Today nothing remains of the first chapel constructed in 1707, but its location was respected and in its place stands the Cathedral of San Isidro. By the end of the XVIII century San Isidro was already important, its territory included the present districts of Vicente Lopez, San Fernando, part of 3 de Febrero and also Belgrano. In all these years, the land destined for farming happened to be the place of rest and leisure of the families of the Buenosairean aristocracy. Additionally, important residences surrounded by immense gardens were constructed that gave San Isidro that particular aspect that with time got to distinguish it.
- Tren de la Costa (Coastal Train) -
The route runs along the Plate River. First serviced by British built trains, the line was cancelled in the 1980s when cost exceeded revenues. In the early 2000s operational rights were bought out by another corporation and a tourist/sightseer train line was brought into service connecting Olivos and Tigre with 11 stops/stations in between. The old English style stations were refurbished and some constructed anew. The vintage stations have a certain charm with their small shops selling refreshments and gifts, making them attractions in themselves.
The “Tren de la Costa” (turistic-passenger train) travels across Martínez in the way from Olivos to Tigre. Mitre train, in Tigre’s branch, has it own station in Martínez and is the quickest way to go to downtown Buenos Aires and the “Delta”. The main avenues, Santa Fe and Del Libertador, are the axis in Northern Suburbs the way to get to Downtown if you travel by car or bus (connection with subway).
