The Bächle are the narrow, stone-lined water channels that run beside the streets of Freiburg's old town, carrying water from the river Dreisam past shops, cafés and tram stops. They have flowed through the city since the Middle Ages and are now its best-known symbol. Local legend says that if you step into one by accident, you will marry someone from Freiburg.
The Bächle at a glance
- Where: along most streets and lanes of the old town, from the Schwabentor and Oberlinden down to Kaiser-Joseph-Straße, Münsterplatz and Rathausplatz.
- Built: probably when Freiburg was founded in 1120; the first written mention of a Bächle dates from 1220.
- What it is today: an open water network maintained by the city, where people cool their feet and children float boats. It once supplied water for animals, fields and firefighting.
- Time needed: you will cross them all over the old town anyway; allow 30–60 minutes if you want to follow the water on purpose.
From medieval water supply to city symbol
Archaeologists believe the channels already existed when the Zähringen dukes founded Freiburg in 1120, about a century before a document of 1220 first mentions one. The water is diverted from the Dreisam, enters the network at the Schwabentor and flows through the town on a gentle natural slope. The Bächle were never the drinking water supply, which came from springs in the hills, but they watered animals and fields outside the walls, carried away rainwater and dirt, and kept water ready for firefighting. A fire regulation of 1838 even told the fountain masters to steer the flow towards the area of a blaze.
For centuries the Bächle ran down the middle of the streets; between 1840 and the early 1850s they were moved to the edges, where most still run. During the bombing raid of 27 November 1944, when the water mains were destroyed, they helped to put out fires, and they were running again by the early 1950s. Since the centre became a pedestrian zone in 1973, covered sections have been reopened, for example on Universitätsstraße in 1986. City workers known as Bächleputzer clear leaves and rubbish from them twice a day, and once a year, in autumn, the whole network is drained for cleaning and repairs.
What to look for
- The changing width: about 75 centimetres near the Schwabentor, the widest point, and only about 15 centimetres in some narrow lanes.
- Marktgasse, where the Bächle still runs down the middle of the lane, as all of them once did.
- Oberlinden, the main distribution point of the network, with an old lime tree planted in 1729 that is watered from the channels.
- The small brass valves set into the stone: 142 of them regulate the flow, and overflow sills keep the water out of cellars.
- The crocodile in the Gewerbekanal on Gerberau: a granite head about a metre long by the stonemason Ole Meinecke, made as a student project in 2001 and placed in the canal in 2002.
- Children floating small boats down the channels on warm days; Bächle boat races are also held for children.
The legend of the wet foot
Freiburgers like to say that anyone who steps into a Bächle by mistake will marry a man or woman from Freiburg. It is only a legend, but a popular one: even the former chancellor Gerhard Schröder put his foot in one in June 2001 on his way to the town hall. In practice the channels are easier to step into than you might think, because they sit flush with the pavement and are easy to miss when you are looking up at the façades.
Tips for your visit
- Come on a warm afternoon to see people sitting on the kerb with their feet in the water. Paddling is fine; drinking the water is not.
- Watch your step, especially in crowds, after dark or with a phone in your hand. On a bike, cross the channels at a right angle rather than riding along them.
- Follow the water uphill from Kaiser-Joseph-Straße towards Oberlinden and the Schwabentor: it leads you through some of the quietest corners of the old town, including the canal lanes of Fischerau and Gerberau.
Nearby
- Freiburg Minster: the Gothic cathedral on Münsterplatz, known for its openwork stone spire, with a farmers' market on the square around it.
- Old Town Hall: the red-painted Renaissance building on Rathausplatz, a few minutes' walk from the Minster.
- Schwabentor: one of the two surviving medieval city gates, at the eastern edge of the old town, close to where the water enters the network.
- Martinstor: the other medieval gate, on Kaiser-Joseph-Straße, with trams running through its arch.
