Kinshasa and Brazzaville are the two closest capital cities in the world. They are separated only by the Congo River. Kinshasa is the capital of the Democratic Republic of the Congo (DRC), while Brazzaville is the capital of the Republic of the Congo. The distance across the river is less than 1 mile in some places. Despite their proximity, there is currently no bridge connecting the two cities; travelers must use ferries to cross. They are the only two capital cities in the world that are in direct sight of each other, creating a unique urban landscape where two different nations and cultures exist within shouting distance across the water.
