Rio de Janeiro (Rio) is the second-most populous municipality in Brazil and the sixth-most populous in the Americas. Rio de Janeiro is the capital of the state of Rio de Janeiro, Brazil’s third-most populous state. Part of the city has been designated as a World Heritage Site, named “Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea”, by UNESCO as a Cultural Landscape. The home of many universities and institutes, it is the second-largest center of research and development in Brazil, accounting for 17% of national scientific output according to 2005 data. Despite the high perception of crime, the city has a lower incidence of crime than Northeast Brazil, but it is far more criminalized than the south region of Brazil, which is considered the safest in the country. Rio de Janeiro wheelchair access is good (by South American standards). The 2016 Olympics and paralympics saw the city lift its game somewhat to support disability travel for the Paralympics. Rio is one of the most visited cities in the Southern Hemisphere and is known for its natural settings, Carnival, samba, bossa nova, and balneario beaches such as Barra da Tijuca, Copacabana, Ipanema, and Leblon. In addition to the beaches, some of the most famous landmarks include the giant statue of Christ the Redeemer atop Corcovado mountain, named one of the New Seven Wonders of the World; Sugarloaf Mountain with its cable car; the Sambódromo (Sambadrome), a permanent grandstand-lined parade avenue which is used during Carnival; and Maracanã Stadium, one of the world’s largest football stadiums.
