Armenia is found in the world’s oldest maps and history books. Sometimes as an independent state, and sometimes divided between neighbouring empires, but nevertheless the name Hayastan-Armenia has always been mentioned since ancient Greek and Roman maps to this day.

Armenia on ancient maps

The oldest extant map of the world is depicted on a clay tablet. It is the Babylonian map found in Iraq, in 19 century. Now it is stored in the British Museum.
This Babylonian map of the World dates back to 6 century BC. In ancient Assyrian and Babylonian sources the kingdom of Ararat is referred to as Urartu. This name is mentioned on the world’s oldest map. Of the countries mentioned in this map, only Armenia still exists. All the other ones have disappeared from the world map.
