Things to do in Stuttgart.

25 attractions worth the trip, with the practical detail a first-time visitor actually needs: how to get there on the S-Bahn and Stadtbahn, how long to allow and what the building or the collection is really about.

Stuttgart is the city where the automobile was commercialized, so the Porsche Museum in Zuffenhausen and the Mercedes-Benz Museum in Untertürkheim sit at the top of most itineraries, and they are the one pairing you cannot make anywhere else on earth. Beyond the cars: the world's first concrete television tower, a zoo built inside a Moorish palace, a UNESCO-listed modernist housing estate from 1927, and a downtown that sits in the Kessel, the bowl-shaped valley the city was built inside.
