 The influx of the Alamanni into northern, eastern and central Switzerland followed a period when the area had fallen under Roman rule and was sparsely settled.Prior to that, the region was inhabited by Celtic peoples.The hamlet of “Züberwangen” was first mentioned in the Henauer Urkunde ("Deed of Henau") of 754, wherein property in Züberwangen, along with property in some other hamlets, all owned by a man named “Rotphald” was deeded to the Abbey of St. Gall.
