What were all of the floors of a ziggurat used for?

Ziggurats were multi-tiered structures that served as temples in ancient Mesopotamia. Each floor typically had a specific function, with the lower levels often used for storage and administrative purposes, while upper levels housed shrines and altars dedicated to deities. The highest level, usually the most sacred, was reserved for rituals and offerings. Overall, ziggurats were central to both religious practices and the societal organization of the cities they dominated.
