Gebel Barkal is a rock structure in Sudan involved with temples and tombs mostly done during Nubian dynasty of ancient Egypt, then worked on more later up to Roman empire's involvement in Egypt. At one end of the rock is a stone pillar said to resemble a rearing cobra (not everybody can see this). My model is made to resemble wondermovie in CIV6 (using Mt Sinai & fragments of other models around).
