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.
