The oldest known world map is the Babylonian Map of the World known as the Imago Mundi.  This map dates back to the 6th century BC. This map, found in southern Iraq in a city called Sippar, shows a small bit of the known world as the Babylonians knew it centuries ago. This map was formed out of a clay tablet and was found north of the ancient city of Babylon, on the fertile east bank of the Euphrates River.
However, more extraordinary fact is that one of the three countries marked on the Babylonian clay slab-map of the 6th century BC is Armenia, which means that we have had our place on the world map for more than 2600 years.
