Activitate Annecy, France
Discover the incredible, hidden story of Lac d'Annecy. Today, it sparkles as Europe's cleanest lake, but in the 1950s, it was a dying, foul-smelling biological dead zone. Join an urban planner and a local environmental historian as they guide you through the political miracles, the scientific awakenings, and the massive, invisible engineering feats that resurrected these alpine waters. This is a story of civic courage, ecological stewardship, and the power of a community that refused to let its natural heritage slip away.
