Rocinha is the largest favela in Brazil, located in Rio de Janeiro's South Zone between the districts of São Conrado and Gávea. Rocinha is built on a steep hillside overlooking Rio de Janeiro, and is located about one kilometre from a nearby beach. Most of the favela is on a very steep hill, with many trees surrounding it. Around 200,000 people live in Rocinha, making it the most populous favela in Brazil.
Although Rocinha is officially classified as a neighbourhood, many still refer to it as a favela. It developed from a shanty town into an urbanized slum. Today, almost all the houses in Rocinha are made from concrete and brick.
