Plaza Aberastain, Public square in San Juan, Argentina.

Plaza Aberastain is a public square in San Juan with green spaces, trees, benches, and paved walkways that link different sections together. The space features an open layout with multiple areas for resting and moving through.

The square existed before 1914, when the monument to Antonino Aberastain was inaugurated and gave it its name. In 1937, under Governor Juan Maurín, a project to declare it a plaza was approved, but work stalled after the 1944 earthquake. The definitive layout was built from 1948 as part of José Manuel Felipe Pastor's regulatory plan, with the design by architect Daniel Ramos Correas.

The square takes its name from Antonino Aberastain, the San Juan governor assassinated in 1861, whose monument was inaugurated here in 1914. The layout by architect Daniel Ramos Correas, with a central east-west pedestrian channel and diagonal ramps from the four corners, shapes how people cross it daily. Kiosks were planned at the corners.

The square lies four blocks (400 m) east of Plaza 25 de Mayo, bounded by Rivadavia, Mitre, Aberastain and Caseros. Diagonal paths with gentle ramps lead from the four corners to the central fountain, so the middle is reachable without stairs. Kiosks were planned at the corners.

The square's layout follows Daniel Ramos Correas's design: a wide east-west pedestrian channel aligned with the surrounding sidewalks, plus two diagonal paths that climb gentle ramps from the four corners to the central space. Ramos Correas planned kiosks at those corners.
