Karlsplatz to the Naschmarkt: the Jugendstil and the market
A baroque dome, a golden one, Otto Wagner's pavilions, and the long market row. This is a Claude-drafted route awaiting the editor's walk.

1. Karlskirche
Start at the *Karlskirche* (the baroque church) — the great green dome flanked by two carved columns, mirrored in the long reflecting pool out front. Sit on the pool's edge first; the building was built to be seen from exactly here. Inside, a lift takes you up under the cupola frescoes if the works are running.

2. Otto Wagner Stadtbahn pavilions
Cross to Otto Wagner's two little *Stadtbahn* pavilions on the *Karlsplatz* — white and gold Jugendstil, 1898, jewel-box scale. One is a small museum, one a café. Walk around both; the sunflower motifs are the whole argument of the era in miniature.

3. Secession
The *Secession* building's golden filigree dome — the locals call it the golden cabbage — announces the breakaway artists who built it in 1898. Down in the basement is Klimt's *Beethoven Frieze*. Go for the frieze; the gilded dome is the free part.

4. Naschmarkt
Drop into the *Naschmarkt*, the long market hall row that runs southwest along the old river course. Walk the whole length once before buying anything — the stalls shift from produce to spice to sit-down *Beisls* as you go. Mornings are for shopping, not lunch.

5. Majolikahaus
Look up across the *Linke Wienzeile* at Otto Wagner's *Majolikahaus* — its whole facade tiled in a climbing flower pattern, the building next door studded with gold medallions. The market noise below, the Jugendstil above; that's the corner.

6. Kettenbrückengasse
The far end of the market, where the *Saturday flea market* sprawls along the pavement if it's the day for it. The U4 at *Kettenbrückengasse* takes you out — Otto Wagner designed this station too, so you finish where the morning's theme began.
