The history of Partido de Rojas

Open farm country near Rojas
Last reviewed 5 October 2026 · A two-minute read · 1777–1960

Partido de Rojas grew from a frontier guard post raised in 1781 to defend the settlement founded in 1777. Open farm country still surrounds the town, which later gained a parish, two public libraries, and a correspondence trail linking Ricardo Rojas to Miguel de Unamuno.

The short answer

Rojas, a farming town in Buenos Aires province, grew up near a frontier guard post built in 1781 to defend the settlement from raids. No building marks this particular stretch of ground, though nearby stand the Rojas guard site and two public libraries that later served the growing town.

1781 and after

A frontier guard once watched this open country

You're standing on quiet ground outside Rojas, a farming town in Buenos Aires province. No building marks this exact spot.

About three quarters of a mile off stands the site of the Rojas guard, a fort built in 1781 to defend the frontier, where soldiers posted there once watched this same open country for raiders. A little closer, two public libraries, the Biblioteca Popular Juan Bautista Alberdi de Rojas and the Biblioteca Popular Pública Municipal W. T.de P.de Galiano, opened decades apart to serve the growing town.

1932 to 1960

Two libraries rose nearby as Rojas grew

The two libraries opened 28 years apart, both built to give Rojas families books and a reading room as the town grew around this open farmland.

The fields around you still farm the same open country the fort once guarded.
