Hidden beneath Munich’s bustling streets flows the Schwabenbächl. A small stream perhaps but its history is surprisingly rich. The Schwabenbächl is a vital part of Munich’s northern canal system. It begins its journey as a continuation of the Hartmannshofer Bach. It emerges from the Allacher Lohe a lake also known as the Hundesee. The Schwabenbächl then flows north. It travels under the A99 motorway before finally joining the Würmkanal.
This unassuming stream played a crucial role in Munich’s development. In 1927 a public water cooperative was formed. The cooperative’s aim was to regulate the Schwabenbächl and improve drainage in the surrounding Ludwigsfeld area. West of the ‘Zur Lüfte’ inn they built a sluice. This sluice diverted water from the Schwabenbächl into the Metzgerbach. Some maps also call this the Schwabenbächl I. The Metzgerbach in turn supplied the Ludwigsbad also known as the Wagnerbad.
Between 1936 and 1940 the Schwabenbächl served as a waterway for wastewater from the BMW Allach plant. To accommodate this function the stream was rerouted. This relocation to the east of Dachauer Straße led to the construction of a bridge. This bridge is now on the Karlsfelder Straße. Since 2017 this bridge has been a registered architectural monument. Before its rerouting the Schwabenbächl flowed into the Würmkanal about 1.2 kilometers further west. Initially though it emptied directly into the Würm River northwest of Karlsfeld.
Today the Schwabenbächl continues its quiet journey. It might not be as dramatic as other Munich landmarks. Its quiet existence however holds a significant piece of Munich’s past. It whispers stories of cooperation engineering and industrial growth. The next time you are near Ludwigsfeld remember the Schwabenbächl. Remember its quiet yet powerful story.
