Criterion (iv): The typology of the buildings, their details and the layout of the ensemble of the pyramids of Gebel Barkal, Nuri and Kurru with their steep angles and decorated sides, together with the painted rock-cut burial chambers, represent an outstanding example of funerary architecture and distinctive art that prevailed over a long period of time (9th Century BC- 4th Century AD). The mounds of Zuma represent a continuation of some aspects of this burial tradition up to the 6th Century AD.
