Kigali, officially the City of Kigali also known as Kigali City, is the capital, largest city, and a province-level administrative unit of Rwanda. It is located near the country's geographic centre, in a landscape of rolling hills marked by valleys and ridges connected by steep slopes. As Rwanda's primate city, Kigali is a relatively young urban centre. Founded in 1907 as a German administrative outpost, it served as a minor administrative centre until it became the national capital at independence in 1962, shifting the main administrative focus away from Huye.
