A team of researchers had discovered a set of small pyramids at Sedeinga, a site in Sudan, between 2009 and 2012. They now suspect to what extent the pyramids are concentrated.

The pyramids are nearly 2,000-years-old when Kush named kingdom prospered in Sudan Necropolis. It has been found that the kingdom used to share a border with Egypt. Later, the same was shared with the Roman Empire.

As per the findings, a total of 35 pyramids have been located along with graves. Of all these, 13 pyramids were found across nearly 5,381 square feet in the year 2011 in one field season alone. The area covered was a bit larger as compared to an NBA basketball court.

Researchers are of the view that the building of pyramid has continued for many centuries at Sedeinga. Egyptian funerary architecture had probably prompted the people of the Kush kingdom to create pyramids.

It is being said that the biggest pyramids discovered are almost 22 feet wide at base. "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", said the American Museum of Natural History's research associate Vincent Francigny.
