Ku. 1

El-Kurru was the first of the three royal cemeteries used by the Kushite royals of Napata, also referred to as Egypt's 25th Dynasty, and is home to some of the royal Nubian Pyramids. It is located between the 3rd and 4th cataracts of the Nile about 1 mile west of the river in what is now Northern state, Sudan. El-Kurru was first excavated by George Reisner in 1918 and 1919 and after his death his assistant Dows Dunham took over his work and published the excavation report on El-Kurru in 1950.
