In Roman era, along Pfäffikersee there was built a Roman road from the vicus Centum Prata on Obersee–Lake Zürich via Vitudurum to Tasgetium 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 neighbouring village of Kempten. Pfäffikon is first mentioned in 811 as faffinchova. In 965 it was mentioned as haffinchova.
