The city lies at the foot of Mount Entoto, and is home to Addis Ababa University. Addis Ababa University was formally known as Haile Selassie I University, after the former Emperor of Ethiopia.
Haile Selassie helped form the Organization of African Unity in 1963 and invited the new organization to maintain its headquarters in the city. The OAU was dissolved in 2002 and replaced by the African Union, also headquartered in Addis Ababa
Of note is the general lack of any street names in the city.
