What is the significance of ziggurats?
Answer according to Wikipedia: “According to Herodotus, at the top of each ziggurat was a shrine, although none of these shrines has survived.[1] One practical function of the ziggurats was a high place on which the priests could escape rising water that annually inundated lowlands and occasionally flooded for hundreds of miles, as for example the 1967 flood.[5] Another practical function of the ziggurat was for security. Since the shrine was accessible only by way of three stairways,[6] a small number of guards could prevent non-priests from spying on the rituals at the shrine on top of the ziggurat, such as cooking of sacrificial food and burning of carcasses of sacrificial animals.
