Human geography

Luanda is divided into two parts, the Baixa de Luanda (lower Luanda, the old city) and the Cidade Alta (upper city or the new part). The Baixa de Luanda is situated next to the port, and has narrow streets and old colonial buildings. However, new constructions have by now covered large areas beyond these traditional limits, and a number of previously independent nuclei — like Viana — were incorporated into the city.
