Current stadium · CA San TelmoEstadio Dr. Osvaldo Baletto

It is San Telmo's ground on Isla Maciel, at Las Heras and Vieytes, just metres from the Riachuelo. The club arrived there after being evicted in 1926 from its Azopardo and Garay ground and played its first official match there in November 1929, against Alvear. Since 1983 it has been named after Dr. Osvaldo Francisco Baletto. It was closed between February 2006 and October 2011, following incidents against Talleres de Remedios de Escalada, and in 2015 the new concrete Las Heras stand was opened, raising its capacity to around 10,000.
