M'banza-Kongo (Portuguese pronunciation: [ɐ̃ˈbɐ̃zɐ], [ĩˈbɐ̃zɐ], [mɨˈβɐ̃zɐ] or [miˈβɐ̃zɐ ˈkõgu], known as São Salvador in Portuguese from 1570 to 1975), is the capital of Angola's northwestern Zaire Province. M'banza Kongo (properly Mbanza Koongo or Kôngo in most acceptable orthographies) was founded some time before the arrival of the Portuguese and was the capital of the dynasty ruling at that time (1483). The site was temporarily abandoned during civil wars in the 17th century. It lies close to Angola's border with the Democratic Republic of the Congo. It is located at around and sits on top of an impressive flat-topped mountain, sometimes called Mongo a Kaila (mountain of division) because recent legends recall that the king created the clans of the kingdom and sent them out from there. In the valley to the south runs the Luezi River.
The earliest documented kings referred to their city in their correspondence as "the city of Congo" (cidade de Congo), and the name of the city as São Salvador appears for the first time in the letters of Álvaro I (1568–1587) and was carried on by his successors. The name was changed back to "City of Kongo" (Mbanza Kongo) after Angolan independence in 1975.
When the Portuguese arrived in Kongo, Mbanza Kongo was already a large town, perhaps the largest in sub-equatorial Africa, and an early visitor of 1491 compared it in size to the Portuguese town of Évora. During the reign of Afonso I, stone buildings were added, including a palace and several churches. The town grew substantially as the kingdom of Kongo expanded and grew, and an ecclesiastical statement of the 1630s related that 4,000-5,000 baptisms were performed in the city and its immediate hinterland (presumably the valleys that surround it), which is consistent with an overall population of 100,000 people. Of these, perhaps 30,000 lived on the mountain and the remainder in the valleys around the city. Among its important buildings were some twelve churches, including São Salvador, as well as private chapels and oratories and an impressive two-story royal palace, the only such building in all of Kongo, according to the visitor Giovanni Francesco da Roma (1648).
The city was sacked several times during the civil wars that followed the battle of Mbwila (or Ulanga) in 1665, and was abandoned in 1678. It was reoccupied in 1705 by Dona Beatriz Kimpa Vita's followers and restored as Kongo's capital by King Pedro IV of Kongo in 1709. It was never again depopulated though its population fluctuated substantially during the eighteenth and nineteenth century.
Notable Sights 
M'banza Kongo is known for the ruins of its 16th century cathedral (built in 1549), which many Angolans claim is the oldest church in sub-Saharan Africa, although this is not true, the oldest is Vera Cruz, built in 1491 so named because it housed a cross-shaped stone found nearby when the first missionaries arrived. The present day church, called São Salvador, known locally as nkulumbimbi, is now said to have been built by angels overnight. It was elevated to the status of cathedral in 1596. Pope John Paul II visited the site during his tour of Angola in 1992.
Another interesting site of historical significance is the memorial to King Afonso I's mother near the airport, which commemorates a popular legend that began in the 1680s that the king had buried his mother alive because she was not willing to give up an "idol" which she wore around her neck.
Other important sites include the Jalankuwo, the Manikongo's judgement tree, can still be found in the downtown area of the city, along with sunguilu, a rectangular ground level structure where local tradition says the king's body was washed before burial, both on the grounds of the royal palace and present day Royal Museum.
The Royal Museum, recently rebuilt as a modern structure, houses an impressive collection of artifacts from the old Kingdom, even though many were lost from the older building during the Civil War of 1976-2002.
