Gorges du Sierroz
The project consists of various interconnected interventions.
A 900-meter-long promenade, fully accessible to people with reduced mobility, has been restored for public use, featuring various amenities along the way.
The historic building on the site (a former mill and sawmill) has been transformed into a museum hall at the entrance of the promenade.
Different engineering structures, such as footbridges and cantilevered walkways, punctuate the path.
Three materials were used for all structures:
+Wood: naturally rot-resistant oak and chestnut, sourced from French forests.
+Metal: hot-dip galvanized steel, produced in France.
+Stone: sand, gravel, and solid stone, extracted directly from the Grésy-sur-Aix quarry, 300 meters from the site.
The constructed structures blend seamlessly into the gorges carved by the Sierroz torrent, offering a journey between natural space and historical heritage.
The metal framework elements are anchored into the rock with tie rods reaching up to 17 meters in length.
The oak wood pieces, arranged in horizontal layers on the footbridge and museum hall, are assembled using a simple interlocking system without screws, directly attached to the metal framework.
The steel structure of the hall features an 18-meter cantilever to enhance and showcase the preserved historical constructions of the old mills and sawmill.
The landscape and architectural project for the Gorges du Sierroz pays tribute to the region, its industrial, historical, and tourist heritage. The choice of materials is intentionally limited so that the structures blend into the landscape, allowing nature and the Sierroz River to take center stage.
