The remainder of Kigali's suburbs lie to the east of the CBD, with an urban sprawl spanning the many hills and ridges. Kiyovu is the closest, on the eastern slopes of Nyarugenge Hill. The higher part of Kiyovu, to the south of main road KN3, has been home to wealthy foreign residents and Rwandans since colonial times, with large houses and high-end restaurants. The residence of the Rwandan president is located in this area. The lower part of Kiyovu, north of the main road, consisted until 2008 of informal settlements that had formed after independence, when strict residence rules were relaxed. The houses in lower Kiyovu were expropriated by the government in 2008 with residents compensated or relocated to other areas, including to a purpose-built estate in the Batsinda neighbourhood. The government has plans to create a new business district in lower Kiyovu to complement the existing CBD, although as of late 2017 there had been only a handful of buildings erected there. Other eastern suburbs include Kacyiru, home to most government departments and the office of the president; Gisozi, where the Kigali Genocide Memorial is located; Nyarutarama, an affluent suburb housing the city's only golf course; Kimihurura; Remera and Kanombe, from the CBD on the eastern edge of the city, where Kigali International Airport is located.
