What city-state worshiped Zeus?

Zeus was the lord of all of the Grecian gods, so his place in Greek mythology was prevalent. He was an all-powerful being, who had overthrown the Titans, including his father, Kronos.

The major place where people paid honor to Zeus was Olympia. Mount Olympia was supposedly where the gods resided, and the major festival in Olympia had the famous Olympic Games. An altar to Zeus made of ash resided in Olympia.
