Paris
Haussmann did not mean to build a heat-adapted city, but he did. The 1850s rebuild fixed Paris at a uniform six-story cornice on streets narrow enough that the buildings shade themselves for most of the afternoon — and the Marais, older and tighter, does it better. The summer sun tops out near 65° here, low enough that a stone wall on the south side of any rue throws a usable shadow until evening. Our routing reads the geometry someone already engineered.

- 01Place de la Concorde to the Arc de Triomphe
The Champs is the exception that proves the rule — a boulevard wide enough that the cornice loses. We hug the north plane trees until Rond-Point.

17th-century arcades hand off to a pre-Haussmann street grid the sun barely finds at noon. The Marais is the city at its coolest by accident of cadastre.

The Champ-de-Mars is honest about its sun and the tower throws a thin moving stripe we do not pretend is a route. We send you via Iéna’s embassy sidewalk.
