Zeus Mountain was the highest part in all of Pandora's Temple. It's beyond the Architect's Tomb, which sat at the very top of the Cliffs of Madness. Upon Zeus Mountain was a Statue of the head of Zeus himself, with a doorway beneath it. The doorway lead to a winding staircase, which lead to the final room of the temple, the Hall of Trials. Beyond that chamber was the main prize of Kratos in God of War, Pandora's Box. Zeus Mountain wasn't visible in any exterior shots of Pandora's Temple in God of War; however, it could be seen atop Pandora's Temple when Kratos fought Cronos in God of War III.
