Swiss Plateau
Alemannic graves appear south of the Rhine, in the Swiss Plateau, from the 6th century. Alemannic colonization of the Swiss plateau apparently took place from the Basel area, since the number of graves there declines simultaneously. Significant influx of Alemannic settlers to the Swiss plateau begins only in the 7th century. Grave fields from this period include one at Elgg-Ettenbühl near Winterthur; with 340 graves it is the largest field south of the High Rhine.
