Stone Age pottery and medieval graves with swords and jewelry are some of the archaeological treasures that have been found.

Archaeologists discovered a grave from the Neolithic, or Stone Age, that was made of pottery from the Corded Ware culture. swords, lances, shields, bone combs, drinking glasses and earrings were among the items found in the early medieval graves.

Mayor Martin Numberger said in a statement that the district is older than they had thought. Based on the first written records of settlement there, the district was originally dated to 12 73.

A team from the firm ArchaeoTask made the discoveries near the river where a retention pond is planned. The Stone Age grave shows the presence of the The Corded Ware people, who are known for their pottery decorated by geometric lines formed by pressing cord into clay and leaving the impressions to dry. The people who kept animals such as cows and sheep were probably pastoralists. Graves from this time period are very rare in southwestern Germany.

The end of the Western Roman Empire in 476 A.D. resulted in the deaths of many people. When various tribes in Europe moved around, pushing each other into new territories, it's known as the Migration Period. The transition between antiquity and the Early Middle Ages is considered by historians.

Men and women are buried with weapons in other graves from this time period. As conquerors took over a village, burial rituals might change. The Alemanni were defeated by the Franks and absorbed into the Merovingian.

The Alemanni began burying the dead of their households in the same graves which held rich goods like armor and jewelry. The study found that the members of the household weren't related by blood and that adopted members of the family were valued equally to those born or married into it.
