St. Antonius Chapel

You will find the old center of the village around the parish church of St. Andreas. The church itself is also worth seeing.

There was already a Rhine crossing near Au am Rhein in Roman times, as evidenced by a Roman milestone that was walled into the tower of the parish church until 1811 (since then in the Badisches Landesmuseum in Karlsruhe). According to this, a Roman road from Baden-Baden crossed the Rhine here. Traces of a Roman settlement were found in 1898 in the "Grubenäcker" area.

Until well into the 20th century, Au was a small farming community, although agriculture always suffered from the unregulated flow of the Rhine. On the other hand, the river offered additional income opportunities through fishing and duck fishing, gold panning and towing ships.
