Archaeologists have discovered the tomb of an unknown ancient Egyptian pharaoh near Abydos, a historic city in Egypt. The limestone burial chamber, about 23 feet underground, dates back around 3,600 years to a period of unrest known as the Second Intermediate Period.

The burial chamber for the unnamed ruler was found in January in a sacred city where little is known about its ancient royalty.
