The city has a main urban area but many other urban, suburban and rural areas exist within the modern city's limits. The main suburban area extends a considerable distance to the east, west and south of the centre, and it includes the former cities of Gloucester, Nepean and Vanier, the former village of Rockcliffe Park (a high-income neighbourhood which is adjacent to the Prime Minister's official residence at 24 Sussex and the Governor General's residence), and the communities of Blackburn Hamlet and Orléans. The Kanata suburban area includes the former village of Stittsville to the southwest. Nepean is another major suburb which also includes Barrhaven. The communities of Manotick and Riverside South are on the other side of the Rideau River, and Greely, southeast of Riverside South.
