Wedding: the flak tower and the Humboldthain
A WWII flak-tower ruin you can climb, a rose garden, and the tunnels under the city. This is a Claude-drafted route awaiting the editor's walk.

1. Gesundbrunnen
The big northern interchange — S-Bahn ring, U8, regional lines. Come out on the *Brunnenstraße* side and the park is two minutes south-west. The Berliner Unterwelten tour meets here, so plan around it (see next stop).

2. Berliner Unterwelten
The meeting point for the underground tours — wartime bunkers, flak-tower interiors, the cut-and-cover U-Bahn used as a shelter. You can't drop in; book ahead. Worth building the whole walk around if the timing works.

3. Volkspark Humboldthain
The people's park, laid out in the 1870s, half-buried after the war under the rubble of the city. Enter from the north and climb gently; this is *Wedding* breathing out — joggers, dogs, allotments at the edges.

4. The Rosengarten
The sunken rose garden in the park's south-west — formal beds, pergolas, a fountain, best from late spring into summer. A deliberate, ordered calm before the brutal thing you're about to climb. Sit a minute.

5. Flakturm Humboldthain
The surviving WWII anti-aircraft tower — too solid to demolish, so the French part-blew it and the city heaped rubble against it. Climb the stair to the platform on top for the view north and west over Wedding and the ring. The structure is raw concrete and the better for it.

6. Brunnenstraße
Drop south out of the park onto *Brunnenstraße* — the long working spine of the *Kiez*, part of the old border for a stretch, now a run of *Spätis* (late-shops), Turkish bakeries and quiet new galleries. Walk it down toward the U8.

7. Voltastraße (U8)
The walk ends on the U8 at Voltastraße. Grab something from a *Späti* on the way; the U8 takes you straight back into the centre.
