The “Ecomusée de la Grande Lande” is located in the Gascogny natural park south of Bordeaux, France. The museum’s several rural sites host exhibitions of the cultural identity and history of this French region, with special insights into how the railway changed the area. The exhibition and documentary Pavilion, opened in autumn 2008, is the latest addition and signals the future direction the museum will take. Designed by architect Bruno Mader, the construction embodies the principles of sustainability and exemplifies the virtuous relationship between architecture and the environment using modernised versions of traditional materials and building techniques. An outer façade of spaced wooden strips gives the impression of a unified whole glimmering in the light. Once inside, however, the building turns out to be a series of grouped volumes, each with its own distinctive function.
