The day begins on a wide avenue of plane trees and café terraces: Cours Mirabeau wakes slowly, pastry steam curling from boulangeries as your guide steers you through Aix-en-Provence’s seventeenth-century palaces and the narrow lanes where Paul Cézanne first sketched light. You move at a walker’s rhythm — pausing beneath carved stone balconies, stepping into Saint-Sauveur Cathedral where centuries of repairs have left a layered face of Romanesque and Gothic stones. The guide’s voice maps social history onto façades: merchants’ plaques, the marble of Hôtel de Ville, the slow commerce of an old provincial capital.
