The Waldensian town of Palmbach is located on the southeastern edge of the urban area and was incorporated into the city of Karlsruhe on January 1, 1975.

Palmbach is located directly at the Karlsbad motorway exit of the Bundesautobahn 8 and is one of the high-altitude districts of Karlsruhe that are called "mountain villages" in the region.

Through the Tausch- und Epurationsvertrag (exchange and purification agreement) of 1806, the place became part of Baden.

During rush hour there is a bus connection every 10 minutes with line 47 to Zündhütle (tram stop) or to the Karlsruhe Hauptbahnhof.

The Waldenserweg with the Waldensian monument Tor des Ankommens (Gate of Arrival) were inaugurated in 2015.

It was designed by the artists Barbara Jäger and OMI Riesterer and found its place on the new Waldenserplatz.
