 Across ancient Greece market places ("agorai") were to be found in most city states, where they operated within the "agora" (open space).Between 550 and 350 BCE, Greek stallholders clustered together according to the type of goods carried - fish-sellers were in one place, clothing in another and sellers of more expensive goods such as perfumes, bottles and jars were located in a separate building.The Greeks organised trade into separate zones, all located near the city centre and known as "stoa."
