The Greeks had sanctuaries in their cities. Sanctuaries were very sacred places, and they had temples in them. Sacrifices were performed there and the sanctuary had a cult statue of a god. An example of a sanctuary is the Parthenon. It is in the rocky hills in Athens and it is Athena's sanctuary. The things that were used in a sacrifice were an altar, a Machiara, barley seeds, and water. A Machiara is a long dagger that was used during the sacrifice to kill the animal that was being sacrificed. The altars were used to burn the animal being sacrificed and they were usually in front of the temples. Altars were usually made of stone and earth but they could also be made of other materials. The barley seeds were thrown by everyone so they all would participate. Water was used to pour on the animals head so it would nod in agreement to the sacrifice.
