The Deputy Director-General of UNESCO for Culture Ernesto Ottone R, Thomas 
Vonier, President of the International Union of Architects (UIA), and Verena Vicentini Andreatta, Municipal Secretary of the City of Rio for Urbanism, announced that the city of Rio de Janeiro will be the World Capital of Architecture for 2020.
“The World Capital of Architecture initiative highlights the common commitment of UNESCO and the UIA to preserve architectural heritage in the urban context,” said Ernesto Ottone R. “Through the breadth and quality of its activities, the World Capital of Architecture in Rio de Janeiro will demonstrate the 
crucial role of architecture and culture in sustainable urban development.”
According to the recent partnership agreement between UNESCO and the UIA, UNESCO designates the World Capital of Architecture, which will also host the UIA World Congress, an event that occurs every three years. The World Capital of Architecture aims to become an international forum for discussions on urgent global challenges from the perspectives of culture, cultural heritage, urban planning, and architecture.
As the first World Capital of Architecture, Rio de Janeiro will hold a series of 
events under the theme “All Worlds. One World” and will promote the 11th Goal of the 2030 Agenda for Sustainable Development, agreed internationally: “Make cities and human settlements inclusive, safe, resilient, and sustainable.”
UNESCO, the UIA, and local institutions will organize activities to promote projects involving architects and urban planners, as well as policymakers, social institutions, and professionals from other sectors, including artists and writers, in an open and creative space for dialogue and innovation.
Rio Through Its Architecture Rio de Janeiro has a lot of landscape architecture to visit. Here are some suggestions:
Historical Overview
When visiting the city center, you will have a historical view, seeing colonial, neoclassical, eclectic buildings, and highlights of modern architecture.
South Zone
Near the beaches facing the Atlantic Ocean lies the affluent South Zone of Rio. It is an urban residential neighborhood with good infrastructure, many restaurants, and shops. In contrast, the favelas coexist in almost every neighborhood.
Port Area
Due to the Olympics, the old port area became the subject of an urban 
redesign project. The plan attempted to bring together historical, economic, and social interests.
Oscar Niemeyer
Among architects, Oscar Niemeyer is the first thought associated with Brazil. Niemeyer’s most famous buildings may be in Brasília, but only in Rio can you learn about his evolution from his first building, a small daycare, to his last constructed work, the complex for the FGV University.
Modern Rio
Modern European architecture strongly influenced the Brazilian movement, but the style was not merely copied. Adapting the principles to the tropical climate and Brazilian culture, architects created a very unique style.
Tropical Landscape Design
Rio de Janeiro has a lot of landscape architecture to visit. You can visit the property and park of Burle Marx, where he planted over 4,000 species. You will see the changes from gardens influenced by Europe to more tropicalized designs using native species.
