This aerial photo shows a series of pyramids and graves that a team of archaeologists has been exploring at Sedeinga in Sudan. Since 2009 they have discovered at least 35 small pyramids at the site, the largest being 22 feet (7 meters) in width. Although the tops are not attached, the base of the pyramids can be seen. The pyramids date back around 2,000 years.
