Sandberg Celtic city
Sitzendorf an der Schmida, Austria
The Sandberg, a hill ridge in the northwestern part of the Weinviertel region of Lower Austria approximately 70 km north of Vienna, is one of the potentially most important archeological sites of the middle La Tène culture in Central Europe. The settlement which flourished there was not fortified, and therefore does not qualify as an oppidum. However, what is known to date suggests that it was not only large (probably covering more than 400, 000 square metres) but also a wealthy and powerful center for trade, culture, religion and political power between southern Bohemia and the Danube valley. Its inhabitants are likely to have been Boii, or belonged to a Celtic tribe that was under their direct influence.
