In the creation myth of the Heliopolitan form of ancient Egyptian religion, Benben was the mound that arose from the primordial waters Nu upon which the creator deity Atum settled.
It was said to have turned into a small pyramid, located in Heliopolis (Egyptian: Annu or Iunu), within which Atum was said to dwell.
[citation needed] Many Benben stones, often carved with images and inscriptions, are found in museums around the world.
The bird deity Bennu, which was probably the inspiration for the phoenix, was venerated at Heliopolis, where it was said to be living on the Benben stone or on the holy willow tree.
In the Amarna Period tomb of Panehesy, the benben is seen as a large, round-topped stela standing on a raised platform.
