Abadía de San Benito, Luján, Buenos Aires Province, Argentina, is a Benedictine monastery of the Cono-Sur Congregation.
On December 8 of that year, the monks relocated to Bellocq, but by 1916 had found rural life untenable, and returned to Buenos Aires.
In the years preceding the Second Vatican Council, the monks devoted particular attention to the renewal of Christian life and culture in the surrounding area.
On October 28, 1950, the monastery was elevated to abbatial status, and Dom Andrés Azcárate (1891-1981) was elected the first abbot of the community.
The monks were forced to consolidate their efforts, abandoning many of their previous apostolates and transferring the monastery to a rural location near Luján on April 12, 1987.
