History.
In Roman era, along "Pfäffikersee" there was a Roman road from the vicus "Centum Prata" (Kempraten) on Obersee–Lake Zürich via "Vitudurum" (Oberwinterthur) to "Tasgetium" (Eschenz) to the Rhine. To secure this important transport route, the Irgenhausen Castrum was built. The native name of the fort is unknown, thus Irgenhausen was mentioned in 811 AD as "Camputuna sive Irincheshusa". Maybe the castrum's name was "Cambodunum", the name of the neighboring village of Kempten.
