Introduction: a large buried valley was discovered in the Viking Age town Hedeby. Results of geochemical analyses and radiocarbon dating point at man-made origin of the structure in the Viking Age. Micromorphological analysis in combination with geochemical methods was aimed to shed light on the use of the valley by humans during the settlement period . Study area (54°29'27.77''N, 9°33'54.42''E): fortified Viking Age town Hedeby, located at the intersection of main transport and trade routes between the Baltic Sea and the North Sea. The settlement was founded in the th th end of the 8 c., and by mid-10 c. it has become one of

the first urban settlements and a major international trading centre in Scandinavia and Northern Europe. However, in 1066 AD the town was destroyed and abandoned.
Despite long-term archaeological investigations in Hedeby, landscape transformation in the central part of the settlement at the brook remained unknown. Therefore, s o i l a n d s e d i m e nt sampling was done in transects along and across the brook by drilling techniques (manual auger and Vibracore system). 0
