It is also the site of an extensive royal palace. The archaeological museum of Vergina was built to house all the artifacts found at the site and is one of the most important museums in Greece. Aigai has been awarded UNESCO World Heritage Site in 1996, as "an exceptional testimony to a significant development in European civilization, at the transition from classical city-state to the imperial structure of the Hellenistic and Roman periods".

Both parks help protect the Cerrado biome, one of the oldest and most diverse ecosystems in the world. For millennia, these sites have served as refuge for many rare and endemic species of fauna and flora, including during periods of climatic fluctuations. Both sites remain essential for maintaining the biodiversity in the Cerrado, especially in any future climate change scenario. The flora of the Cerrado is rich. It includes between 350 and 400 species of vascular plants per hectare, including many endemic plants. The property also contains populations of large mammals, including the giant anteater, giant armadillo, maned wolf, jaguar and pampas deer, but also the rhea, the largest bird of South America. The site is also extremely important in maintaining the hydrological regime as, due to its geological features and soils, it is proving to be a key area for aquifer recharge and the alimentation of several watercourses that supply power to the Amazon basin and the Pantanal, in the basin of La Plata.
