The Middle Danube region is a key area for understanding Upper Palaeolithic hunter-gatherer behaviours in a climatic context due to its long loess–palaeosol sequences and rich archaeological record spanning from the onset of the Upper Palaeolithic to the Last Glacial Maximum and beyond. Recently, new approaches focusing on high-resolution studies of the stratigraphy, geoarchaeological studies at microscopic scale and investigations of organic matter at molecular scale (biomarker analyses) have shown great new insights in human behaviour. Many sites in the Middle Danube region have been excavated a long time ago without opportunity to apply such approaches. The aim of this paper is to introduce Ollersdorf-Heidenberg, a loess open-air site. The site is located ~ 26 km northeast of Vienna close to the Morava River valley and preserves several Upper Palaeolithic archaeological horizons. The site has been known since a pipeline construction in 1998. Here, we report the first results of new research at the site including new excavations in two trenches. We describe and analyse the stratigraphy, present a first radiocarbon date, describe and analyse lithic and faunal collections, and assess potential in situ combustion activity and the preservation of organic matter. Research at the site is ongoing, but our preliminary results let us suggest good preservation of organic matter and, hence, Ollersdorf-Heidenberg has a remarkable potential for providing valuable insights in past hunter-gatherer behaviours at the climatic downturn towards the Last Glacial Maximum.
