Favela Rosinha is considered one of the largest, most densely populated and urbanized slums of Rio de Janeiro, according to unofficial estimates, its population reaches nearly 180,000. Rosinha is located in the southern part of the city between the districts of San Conrado and Gavea, near the respectable residential and tourist areas of Rio de janeiro. Even in Rosigne itself, there are rich and poor areas. Poor neighborhoods are usually on top of a hill, where many houses can only be reached on foot. The shacks are literally “piled” on top of each other, resembling a huge hive. The history of the favela begins in the 1920s, with a hillside settlement near Rio de Janeiro, Portuguese, French and Italian immigrants who organized small farms here. Soon, Rosinha, which means "small farm", becomes the main supplier of fruits and vegetables for the famous open-air market in the Gavea region. In the 1950s and 1970s, immigrants from other parts of Brazil began to settle in Rosigne. The favela infrastructure began to develop, banks, pharmacies, shops, fast food restaurants, night clubs, gyms, clinics, post offices, public schools, kindergartens, cable TV and bus services appeared. Most of the houses are built of brick and cement, many of them today have running water and are almost 99% electrified. The Brazilian government is trying to control the chaotic growth of slums around Rio de Janeiro, so in 2009 the construction of a wall began around Rosinha, restricting the uncontrolled seizure of new territories by favelas on the Atlantic coast. In the framework of the city development plan, it is planned to create a buffer zone - an eco-park with tourist, sports and entertainment facilities. In anticipation of the World Cup in Brazil in 2014 and the 2016 Olympics, Brazilian law enforcement agencies have undertaken a number of operations to combat crime - drug trafficking, arms and robbery. As a result, the criminogenic situation in Rosinje improved, however, government control was never fully established. Recently, this area with beautiful sea views and vibrant nightlife has become increasingly popular with tourists. As a rule, excursions are conducted by travel agencies, which have a tacit non-attack agreement with the local drug lords. Foreign tourists are strongly discouraged from visiting favelas on their own.
