The ancient city of Babylon, first referenced in a clay tablet from the 23rd century B.C., was designated a UNESCO World Heritage site on Friday, after a vote that followed decades of lobbying by Iraq.

The vote, at a UNESCO World Heritage Committee meeting in Baku, Azerbaijan, made the ancient Mesopotamian city on the Euphrates River the sixth world heritage site within the borders of the country, known as a cradle of civilization.

Iraqi President Barham Salih said the city, now an archaeological ruin, was returned to its "rightful place" in history after years of neglect by previous leaders.
