Starting at Oberstadt 3, in the heart of the old town, you'll open the Explorial app, enter the 6-digit game code that you received by text and Viator chat message, and step into a painted storybook. The tour is fully self-guided — no guide, no fixed start time, just your group and the city.
Up at Kirche Burg and the Römerkastell, the riddles reach back furthest: a church standing inside the walls of a late-Roman fort that once watched over the Rhine frontier.
At the Undertor, you'll pass beneath the medieval gate tower that still marks the entrance to the old town — spot the details the app asks about before you walk through.
The Rathaus and its square are the grand finale: town hall, half-timbering, and facades frescoed with knights, merchants, and morals — the richest painted ensemble in Switzerland.
Around 2 hours of storybook streets along the young Rhine. By the end, you'll understand why this little town took home the very first heritage prize.
