Pyramid 4, Jebel Barkal, Sudan, North-east Africa
The physical proportions of Nubian pyramids differ markedly from the Egyptian edifices: they are built of stepped courses of horizontally positioned stone blocks and range approximately 6–30 metres (20–98 ft) in height, but rise from fairly small foundation footprints that rarely exceed 8 metres (26 ft) in width, resulting in tall, narrow structures inclined at approximately 70°. Pyramid 4 (Amanirenas: 40-10 BCE)
