Step-by-step explanation:
Ancient civilizations around the world created large areas dedicated to ceremonial use separated from the outside world. One example is the Acropolis, which was the sacred part of Greek cities and housed temples on top of a hill for defense purposes. Another example is the Ziggurat, a terraced step pyramid built in Mesopotamia and used for religious rituals by authorized religious officials. Additionally, the citadel in cities like Harappa might have served as a monumental ceremonial center for ritual activities and the residence of the ruling elite.
