Discovered between 2009 and 2012, researchers are surprised at how densely the pyramids are concentrated. In one field season alone, in 2011, the research team discovered 13 pyramids packed into roughly 5,381 square feet (500 square meters), or slightly larger than an NBA basketball court.
They date back around 2,000 years to a time when a kingdom named Kush flourished in Sudan. Kush shared a border with Egypt and, later on, the Roman Empire. The desire of the kingdom’s people to build pyramids was apparently influenced by Egyptian funerary architecture.
At Sedeinga, researchers say, pyramid building continued for centuries. “The density of the pyramids is huge,” said researcher Vincent Francigny, a research associate with the American Museum of Natural History in New York, in an interview with LiveScience. “Because it lasted for hundreds of years they built more, more, more pyramids and after centuries they started to fill all the spaces that were still available in the necropolis.” [See Photos of the Newly Discovered Pyramids]
The biggest pyramids they discovered are about 22 feet (7 meters) wide at their base with the smallest example, likely constructed for the burial of a child, being only 30 inches (750 millimeters) long. The tops of the pyramids are not attached, as the passage of time and the presence of a camel caravan route resulted in damage to the monuments. Francigny said that the tops would have been decorated with a capstone depicting either a bird or a lotus flower on top of a solar orb.
