The Aterro do Flamengo is one of the great urbanization projects that transformed Rio de Janeiro's coastline, especially in the area at the entrance to Guanabara Bay. Its creation dates back to the 1960s, when the city, in the midst of a process of population growth and urbanization, faced the need to expand its urban spaces for leisure and housing for the middle and upper classes. The area that today houses the Aterro was originally a region of beach, lagoons, marshes, and sea, seen, however, as a valuable space for the city's expansion.

The Aterro do Flamengo significantly modified the coastline in this stretch of Guanabara Bay, especially the Praia do Flamengo, nestled between the Outeiro da Glória and the Morro da Viúva, two headlands that jutted out over the Bay's waters. The cove formed below the Outeiro da Glória also held a lagoon of historical importance: the Lagoa de Uruçu-Mirim, which was home to one of the largest tabas known in Rio's history. The Tupinambá people who lived there fought alongside the French against the Portuguese in the battle that founded the city of Rio de Janeiro. The Praia do Flamengo, which originally had a different shape, is home to the mouth of the Rio Carioca, which flows down through what is now the neighborhood of Laranjeiras, certainly once surrounded by mangroves and marshes that were completely filled in. Tons of landfill were dumped onto it, coming from cuts and excavations of nearby hills, as well as dredging materials from the bottom of the Bay itself, thus creating a new stretch of sand out into the sea. It was on this space that the famous Parque do Flamengo was built. This transformation extended to Botafogo beach, which was also filled in and had its beach arc artificially reshaped a few hundred meters further out over the sea. The landfill allowed for land reclamation and the construction of new urban areas, including avenues and the Parque, but it also resulted in the modification of the natural profile of these beaches, altering their original geography and affecting the region's coastal dynamics

The landfill was created in response to the increase in industrial and commercial activities in the bay area and the growing pressure for new urban spaces from an increasingly capitalized middle and upper class. It was decided that part of the coast would be filled in, creating a new space that would not only meet the population's leisure needs but also enable the construction of avenues and residential areas. The landfill process began in 1964, during the Castelo Branco administration, and was carried out mainly by the federal government, with the collaboration of the City of Rio de Janeiro. The work basically consisted of reclaiming land from the sea, using large volumes of earth and materials dredged from the bottom of the bay.

Aterro do Flamengo was planned as a large urban park, envisioned to be one of the biggest and most important in Rio de Janeiro, accommodating leisure areas and public facilities, among which the World War II Memorial Monument and the Museum of Modern Art (MAM) stand out. With a landscape design by Roberto Burle Marx, the Aterro houses several cultural and leisure attractions, bordering the Marina da Glória, areas for sports such as soccer, tennis, volleyball, and basketball courts, as well as tracks for model aircraft and model boat flying. The landscaping conceived from the Landscape Architect's design became famous and glorified the work, generating international recognition and a scenic beauty that is, in fact, striking and of its own style. Despite the landscape impact, the ecological impact of the landfill was significant. The area occupied by marshes, mangroves, lagoons, and beaches, essential for marine wildlife and for the protection of coastal zones, was completely modified. The change in the bay's natural dynamics affected water circulation and local ecosystems, compromising the fauna and flora that lived there, though this is still the dynamic of urban space and of our way of inhabiting it. The transformation resulted in a large area that is of great use to the local population and to tourists who are enchanted by the scenic beauty of the cove, framed in the background by the Pão de Açúcar peninsula and Morro da Urca, turning it into one of the most widely known postcard images in the world. In addition, the new avenues that connected the Flamengo region to Downtown and to the South Zone brought about an immense improvement in the city's road circulation.

The project not only expanded the city but also redefined Rio de Janeiro's urban landscape. The Aterro do Flamengo became a symbol of the city's modernization, with its vast park and important traffic routes. The landfill turned into one of the city's most visited leisure and cultural spots, marking a milestone in Rio de Janeiro's urbanization process and development. However, it is impossible to separate this transformation from the significant environmental impact it had on Guanabara Bay, whose dynamics and biodiversity were profoundly altered.
