Estadio Dr. Osvaldo Francisco Baletto

San Telmo did not go looking for a stadium in the city centre. Its ground sits in Isla Maciel, the strip of Avellaneda hemmed in by the port docks, and that placement has shaped the club as much as any result on the pitch — a working port neighbourhood with its own football club, its own ground, its own name for both.

The stadium carries the name of Osvaldo Francisco Baletto, a former club president, and has done since it opened its gates on 24 November 1929. Nearly a century on, no source records a renaming or a rebrand — the name given at the start is the one still in use.

At 7,500, the capacity keeps it firmly a neighbourhood ground rather than anything built for spectacle, and the natural grass pitch has stayed the surface of choice through the decades since. The address, General Rivas 512, places it deep inside Isla Maciel rather than anywhere a casual visitor would stumble across it — this is a ground for people who already know where Dock Sud is.

San Telmo have played here across their history, and the club's own site is where fixtures and news are kept up to date for anyone following the team beyond matchday.
