Kaiseraugst

Geschichte

Kaiseraugst is a municipality in the district of Rheinfelden in the canton of Aargau in Switzerland. It is named for the Ancient Roman city of Augusta Raurica whose ruins are situated nearby. The prefix Kaiser- refers to the fact that this town was part of Further Austria, as opposed to neighbouring Augst, which was in the Swiss canton of Basel.HistoryAbout AD 300, following the loss of the Limes Germanicus and the right bank of the Rhine, the Roman army built a fort near the city of Augusta Raurica. The fort, which was named Castrum Rauracense was intended to serve as the headquarters of the legio I Martia and to protect a ford over the Rhine. During the 4th century, the fort grew in importance because it commanded a bridge that lay along the road from Gaul to the Danube. Emperors Constantius II and Julian assembled their armies at the Castrum Rauracense before marching to battle against the Alemanni.
