Since 1866, Estancia San Martín in Cañuelas has been a pioneer in horse breeding, leading the agricultural and dairy vanguard in Argentina since the beginnings of La Martona. Today, with the enhancement of its historic center, it is reinventing itself as the cradle of the Cañuelas Polo Club, becoming the essential territorial complement for a region recognized worldwide as the cradle of the best polo.
In the dawn of yesteryear, the rhythmic beat of the milk jugs marked the beginning of the day. Today, with the echo of the polo cue finding its target - the ball - the countryside awakens.
two centuries of history

In a region in full agricultural production, the location of the Sociedad Pastoril de Merinos, future lands of the Estancia San Martín.

Hull of the Sociedad Pastoril with the small house and ombú trees. On its side, the Camino Real and, above it, a ditch for protection.

The hoof in full development of sheep breeding.

The old town with the mansion and its tower, the "Galpón de los Merinos" and the "Galpón de los Toros" in a landscape surrounded by a new grove of trees.

View of the park of Estancia San Martín. There are still the fountains oriented along the axis of the old house (1864) and its old park.

1864: construction of the new hull by Vicente Casares. 1990s: addition of a pavilion; annexes for restrooms. 1903: enlargement with reception rooms, new openings and decorated ceilings. 1931: construction of a belvedere; incorporation of neocolonial elements.

1885: initial construction in the style of a French Renaissance palace. 1892: fire that destroyed the 4 corner pavilions; subsequent simplification of the roof. 20th century: housing of Shire and Morgan stallions, followed by La Martona bulls. 1920's: addition of silos for dairy fodder.

1920. First wooden silos based on European and North American models.
Function: accumulation and conservation of fodder for winter seasons, with top loading and side unloading.

A cheese factory, managed by a French master cheesemaker, was installed in the mansion.

First factory of La Martona. The water tank and a Hamburg flagstone floor are still preserved.

The gates belonged to Parque 3 de Febrero and were designed by architect Dormal in 1875.

Avenue of eucalyptus trees (planted around 1869). The seedlings were a gift from Pereyra Iraola to Vicente L. Casares. Today, one of the accesses to the property by Adolfo Cambiaso Street.

Park near the house, where you can see the relatively young palm trees and one of the gas lanterns with which the park was illuminated. Most of the trees are exotic species, in keeping with the style of the time.

"La Leche Cuajada de La Martona", book and first joint collaboration of Jorge Luis Borges and Adolfo Bioy Casares. The name La Martona came in honor of Marta Casares Lynch, Bioy Casares' mother. At that time, the lady who took care of her called her "Martona". That is why his uncle commissioned the young writer to write a booklet in favor of its yogurt predecessor: the successful "leche cuajada" (curdled milk).
