The remains of 16 pyramids with tombs underneath have been discovered in a cemetery near the ancient town of Gematon in Sudan. They date back around 2,000 years, to a time when a kingdom called “Kush” flourished in Sudan. Pyramid building was popular among the Kushites. They built them until their kingdom collapsed in the fourth century AD.
