The Inca worshipped both a creator god and the sun, moon and stars. In this episode, host Christy Kenneally travels to the Peruvian Andes to explore the remnants of Inca civilisation - the city of Pisac, which, like all Inca cities, was designed in the shape of a sacred animal; Cajamarca, where the Inca leader Atahualpa was murdered by the Spaniards; and the sacred mountaintop city of Machu Picchu.
