Welcome to l’Odyssée des Bâtisseurs. In Lac-Saint-Jean, water is omnipresent. Discover how this resource powered the development of the region through the many activities offered by L’Odyssée des Bâtisseurs. Thanks to our indoor and outdoor activities, you will learn how water was a key factor in the growth of our region and its progression towards major industrial development. Our theme starts with the construction of the Isle- Maligne hydroelectric complex – a colossal construction site built between 1923 and 1926 – which transformed the region and its inhabitants. Discover the extraordinary efforts of our “empire-builders” as you visit our displays and participate in workshops, animated performances, and follow a pedestrian path adorned with old ruins and reconstructed vestiges.
