Königsaue is also a middle palaeolithic find spot. It dates to about 80.000 BP, the Eemian (Ipswichian) interglacial. The site most probably was a seasonal hunting camp at the shore of Lake Aschersleben that was completely drained at the beginning of the 18th century by an order of Friedrich II. It was discovered in 1963 by Dieter Mania during rescue excavations in the course of lignite mining (opencast mine Königsaue 1, 1918 – 1977) in a depth of 17 m.

Around 6000 flints have been excavated, including a few bifacially worked knives (Keilmesser) and small pointed hand axes of Micoquien type (Faustkeilblätter). The bifacial tools are most common in layer A, while prepared cores are typical for layer B. Numerous unretouched blades and small debitage point to intense local tool production. The site may have been used as a base camp. In layer C bifacial tools again predominate. Layers A and C belong to the Micoquien, and B to the Mousterian. Animal bones show that mammoths, woolly-haired rhinos, horses, red deer, and reindeer were hunted. Some pieces of worked wood have been preserved as well.
