Matchday at El Monumental
Known affectionately as ‘El Monumental,’ the stadium is famous for its steep, close-to-the-pitch stands that generate an intense atmosphere on River Plate matchdays. Its bowl shape and sheer scale make it one of the loudest and most intimidating venues in South American football, particularly during Copa Libertadores nights and the Superclasico rivalry against Boca Juniors.
A Stadium of Continental Significance
Since opening in 1938, the stadium has undergone several renovations, including the removal of its athletic track and a major redevelopment completed in phases between 2020 and 2023 that expanded seating capacity. In January 2026, club officials announced a further expansion plan aiming to raise capacity toward 101,000 and add roof coverage, a project that would further extend its standing as South America’s largest football arena.
