Castrum Rauracense

Kaiseraugst ( Swiss German: ''Chäiseraugscht'') is a municipality within the district of Rheinfelden in the canton of Aargau in Switzerland. It is named after the Ancient Roman city of Augusta Raurica whose ruins are situated nearby. The prefix ''Kaiser-'' ("imperial") refers to the fact that from medieval times this town formed part of the Habsburg territory of Further Austria, as opposed to neighbouring village of Augst, part of the then Canton of Basel in the Old Swiss Confederacy.

History

About 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, and sometime around 337 and 341 AD, an amphitheatre, likely the youngest known Roman amphitheatre, was constructed. Emperors Constantius II and Julian assembled their armies at the Castrum Rauracense before marching to battle against the Alemanni.

Following the collapse of the Roman Empire the fort remained occupied as local Germanic tribes moved in. The fort and neighboring church became the seat of a bishop during the 4th century, with the bishop first being mentioned in 346. In the 7th century the bishop moved to Basel and the settlement declined in importance. In 752 a village called ''Augusta'' was first mentioned, however it was not until 1442 that the village of Augst split into Augst and Kaiseraugst.

In 894 the East Francian King Arnulf granted the church in Kaiseraugst to his vassal Anno. The church was then granted to the Abbey of St Gall and then later to the Basel Münster. The original church, built in AD 400, was replaced with a new building in 1749. Following the Act of Mediation in 1803 the church was granted to the new canton of Aargau. In 1878 the majority of the community became Christian Catholic and took over the church. In 1900/01 the Roman Catholic church was built and the original church's property was divided.

In the early 1960s, the Kaiseraugst nuclear power plant construction project was met with strong opposition from the population, who occupied the site in 1975. After the Chernobyl disaster, the Swiss government and Kaiseraugst Nuclear Energy AG agreed to abandon the project.
