Five tribes settled on this meteorite made of vibranium and called it Wakanda.
Based on the information from The Art of Black Panther, Wakanda is situated between Uganda, Rwanda and the Democratic Republic of the Congo (approximately, as Lake Kivu doesn’t actually border on Uganda).
Many other photographic reference shots for digital backgrounds, or actual plate photography took place in Africa to create the looks of Wakanda. Some of these locations include: farmlands of Uganda and various areas of South Africa.
