When I think of Sumerians, I think of Cuneiform because it is the first known record of a written language. Sumerians are also known for Ziggurats, but that is a characteristic of most civilizations built around the Tigris and Euphrates rivers. Ziggurats are basically pyramidal structures built for worship, temples.
