Monument to the Carta Magna and Four Regions of Argentina, Stone monument in Palermo district, Buenos Aires, Argentina

The Monument to the Carta Magna and Four Regions of Argentina is a 24.5-metre marble and bronze structure at Del Libertador and Sarmiento Avenues. A statue of the Republic crowns the central pillar, which carries reliefs of many figures. Bronze allegories of the Andes, Río de la Plata, La Pampa and El Chaco stand at the base, and a seated figure with a staff sits above a plaque reading "AL PUEBLO DE LA PLATA". The monument rises from a pool with a fountain jet.

The Spanish community donated this monument in 1910 for the centennial of the May Revolution, but its inauguration took place in 1927 due to construction delays. The lengthy project reflects how important the monument was for recognizing Spanish contributions to Argentine history.

The monument is popularly called Monumento de los españoles, though its official name refers to the Carta Magna and the Four Regions. Its inscriptions quote the preamble of the Argentine Constitution and four statements on the brotherhood of Argentina and Spain. The bronze figures on the base corners represent the Andes, Río de la Plata, La Pampa and El Chaco.

The monument stands in the pool at the Del Libertador and Sarmiento avenue junction, in the Palermo gardens facing the former zoo. It is reached on foot from the surrounding sidewalks; the base and pool are not meant to be entered. Since 2011, 17 LED projectors light it after dark.

In 1991, a two-meter-tall nymph sculpture belonging to the monument was recovered from the seabed after decades, having been lost during a shipwreck in the original construction period. The rediscovery of this missing figure revealed the hidden history of the monument's construction process.
