Be sure to head to the Cathedral square, Münsterplatz, in the morning to see the daily farmer’s market and eat a sausage from the stands there.
At the top of the hill, you’ll find a public park with panoramic views of the city.
Certainly, the Altstadt (old town) is the best place to walk around. The Cathedral and Town Hall have their own squares and the pedestrian shopping streets are there too.
Flammkuchen is a thin crispy dough with cream sauce and toppings. So a bit like a pizza, but not. The classic toppings of onion and bacon are from just over the river in Alsace France.
Each summer, there are music and local festivas in specific sections of town and on the castle hill.
