Each God had their own temple.
Within these temples the Priests or Priestesses made sure that the rules of offering were followed.
The Temples were seen as God`s home on Earth.
Temple designs were based on palaces.
Inside the Temple stood a statue of the God to whom the Temple was dedicated.
Usually at the Temple entrance was an altar where worshippers would bring food, drink, or animals for sacrifice by the priest.
