There is plenty of evidence of our early human ancestors and their ways of life in the area around Korsør. In the wood, "Lystskoven", you will find a remarkable stone setting in the shape of a large ship as well as two circle settings. All of them date from the Stone Age, 3.800 BC. There is also a passage grave near the village of Halseby but the most impressive one is "Rævehøj" near the village of Dalby. The chamber is approximately 2.5 meters high, one of the tallest found in Denmark. It contains Bronze Age carvings.
