Na Příkopě and art-nouveau Prague
The old moat boulevard, the Mucha-era concert hall by the Powder Tower, and the grand banks in between. This is a Claude-drafted route awaiting the editor's walk.

1. Municipal House (Obecní dům)
The art-nouveau showpiece — *Obecní dům*, 1912, every surface worked in mosaic, glass and wrought iron. The *Smetana Hall* inside is the concert room; the café and the American Bar on the ground floor let you in without a ticket. Take a coffee under the painted ceiling.

2. The Powder Tower (Prašná brána)
Right beside the Municipal House, the blackened Gothic *Prašná brána* — a 15th-century city gate that once stored gunpowder, marking where the royal route into the Old Town began. The contrast with the art-nouveau next door is the whole point.

3. Na Příkopě (the moat boulevard)
Walk down *Na Příkopě* — literally 'on the moat', because that's what it was until they filled it in. Now the grand commercial street: 19th-century bank palaces, the odd belle-époque passage cutting between buildings. Look up, above the shopfronts.

4. The bank palaces & passages
Midway down, duck into one of the *pasáže* — covered arcades threading through the blocks, glass-roofed and quiet. The old bank halls along here, marble and brass, are some of the grandest interiors in the city you can simply walk into.

5. Mucha Museum (Kaunický palác)
A short step off the boulevard on *Panská*, in a baroque palace: the *Mucha Museum*, devoted to the painter whose posters defined art nouveau. Small, focused, the Paris theatre posters and the Czech sketchbooks side by side. An hour, no more.

6. Můstek
End where *Na Příkopě* meets the bottom of *Wenceslas Square* at *Můstek* — named for the little bridge that once crossed the moat, a fragment of which sits in the metro station below. Lines A and B both stop here.
