Kinshasa, the capital of the Democratic Republic of the Congo, is located on the southern bank of the Congo, directly across from Brazzaville. To distinguish between the two African countries that have "Congo" in their names, the Republic of the Congo is sometimes called Congo-Brazzaville, as opposed to Congo-Kinshasa. Kinshasa is more than five times larger than Brazzaville in population. This is the only place in the world where two national capital cities developed on opposite banks of a river, within sight of each other.
