Wernigerode sits at the foot of the Harz mountains, a town whose crooked timber houses and colourful facades hide a centuries-long standoff between the counts who ruled from the castle above and the merchants who built their fortunes below. This self-guided walking tour follows that quiet rivalry through gate towers, market squares, and houses that refused to fall down straight. Everything runs from your phone. You get a clear map of all 7 stops, simple directions through Google Maps, and a short audio story with an interactive quiz at each location. The route runs from the medieval Westerntorturm gate through the Marktplatz and its twin-towered Rathaus to the narrowest house in town, finishing with the story of Schloss Wernigerode above the rooftops. The final climb to the castle terrace is optional, so you can either walk all the way up or listen from a viewpoint below. Start anytime, pause whenever you like, and explore freely. No groups, no schedules. Audio and text available in 7 languages. And it comes with a free eSIM, redeemable once per account, so your map, directions and audio work from the moment you arrive, with no roaming charges.
