Джемдет-Наср
Jemdet Nasr () is a tell or settlement mound in Babil Governorate (Iraq) that is best known as the eponymous type site for the Jemdet Nasr period (3100–2900 BC), and was one of the oldest Sumerian cities. The site was first excavated in 1926 by Stephen Langdon, who found proto-cuneiform clay tablets in a large mudbrick building thought to be the ancient administrative centre of the site.
