Munich is where the salt toll was.
The city first appears on 14 June 1158, in an arbitration over who collected the money for crossing the Isar. Eight centuries later it spent 35 million euros giving the river back the shape it had before it was channelled.
Munich sits at about 520 metres on a gravel plain. That is not a metaphor: the ground under the city is material the Isar and the Alpine glaciers left there, a platform of gravels and sands tilted gently northward. Fifty kilometres to the south are the Alps. Nothing interrupts the view between the two, which is why, on a handful of days a year, the whole range is visible from inside the city.
01 Gravel, a fast river and a salt road
The Isar is not a lowland river. It comes down from the Alps with gradient and an irregular flow, dragging gravel and dropping it in bars that shift position. A river like that is hard to cross and easy to ford at very few specific points: the places where the bed widens and shallows.
Across that plain ran the salt route, carrying the product from the deposits of the south-east towards the north and west. Salt was the good that justified a customs post. And a customs post needs a compulsory point of passage: a bridge.
02 14 June 1158
That is the date of the document in which the name of the place first appears: “forum apud Munichen”, the market beside Munichen. It is not a founding charter but an arbitration signed at Augsburg, settling a dispute over who collected the money for crossing the river.
What had happened is simple enough. Henry the Lion, Duke of Bavaria, did away with the existing bridge downstream at Föhring and put up his own a few kilometres upstream, along with a customs house and a coin market. The salt traffic was obliged to pass where he said. The city is, literally, the collection infrastructure of that toll, plus everything that grew around it.
Eight and a half centuries later that market has 1,505,005 inhabitants — the figure for 31 December 2024 — across 310.71 square kilometres and 25 boroughs, at a density of 4,844 people per square kilometre. But from the air the origin is still legible: the old town is a compact oval, streets running out of it like spokes, and the river passing outside it, to one side.
03 The river that was straightened and then bent back
Through the nineteenth century and much of the twentieth, the city's relationship with the Isar consisted of taming it. It was boxed between walls to control flooding, its course was straightened and its gravel bars were taken away. What was left was a straight, efficient channel with its back to the city.
Between 2000 and 2011 the opposite was done. The Isar-Plan remade eight kilometres of river inside the city boundary at a cost of 35 million euros. Walls came out, banks were laid back to a gentle slope, the gravel bars were returned, and flood risk went down at the same time. The aim was double and it worked double: more protection against floods and a river you can walk down to.
The result is the strangest thing this city has. Along the Flaucher stretch, fifteen minutes from the centre by underground, there are banks of white gravel where people lie in the sun, swim in twelve-degree water and barbecue in the designated areas. It is not a river beach dressed with imported sand: it is the river itself doing what it did before it was channelled.
04 And a stationary wave inside a park
The Englischer Garten covers 3.7 square kilometres and was laid out in 1789. The Eisbach, a channelled arm of the Isar, runs through it, and where the water comes out from under a bridge it forms a standing wave a little over half a metre high. It is always there, winter included, and it is surfed in turns.
The real state of things is worth reporting, because it changed recently. In April 2025 an experienced surfer died when her leash snagged under the water, and the wave was closed. It reopened under conditions in June, disappeared completely after the riverbed was dredged in November, and did not form again until May 2026. It can be surfed again today, under new rules: no surfing between 22:00 and 5:30, self-releasing leashes compulsory, and never alone.
05 How you get around
The old town can be crossed on foot end to end in twenty minutes, and almost everything people visit is inside it. For the rest there is underground, suburban rail, tram and bus, in a dense and frequent network. Since January 2026 the national German travel pass costs 63 euros a month and covers all regional transport in the country, which makes it worthwhile on longer stays.
And one practical rule that explains more than it seems to: in this city the interesting things are almost all in a strip of water. The river, the channel through the Englischer Garten, the lakes to the north. Munich organised itself around a river crossing and eight centuries later it is still looking in the same direction.
