 Kigali's CBD, sometimes known in English by the Kinyarwanda term "mu mujyi" ("in town"), is on Nyarugenge Hill and was the site of the original city founded by Richard Kandt in 1907.The house that Kandt lived in is now the Kandt House Museum of Natural History.Geographically, the CBD is situated towards the western edge of the built-up area, as the terrain to the east was more suitable for development of the expanding city than the high slopes of Mount Kigali to the west.
