The whistle blows, the small alpine train climbs out of Nice and the Mediterranean’s scent thins into cedar and chestnut. Windows frame terraced slopes, the Var river carving a green gorge below; the carriage rocks like a promise of old engineering and older borders. Stepping off in a classified village, the air carries stories—stone stairways, a drawbridge that still remembers soldiers' boots, and a castle armored by Vauban's angled walls.
