Beneath the waters of Lake Geneva lies a 3,000-year-old secret: the Port de Tougues, Western Europe's only submerged seaside resort and a fascinating vestige of the Final Bronze Age.
History
Just off the shores of Chens-sur-Léman, a few metres beneath the translucent surface of Lake Geneva, lies one of France's most exceptional archaeological sites. The Port de Tougues is not a monument to be visited by wandering through gilded halls or walking along stone passageways; it can be contemplated with a mask and snorkel, or through the eyes of the archaeologists who have dived in to rediscover it. This underwater site, listed as a Historic Monument since 1997, is the only known coastal station of its kind in Western Europe - a title that alone says everything about the absolute uniqueness of the place. The site belongs to the large family of palafittes, the pile dwellings that flourished on the shores of Alpine lakes between the Neolithic and Bronze Ages. But where most of the palafittic villages have revealed their secrets over the centuries through excavations on land and dried-up sediments, the Port de Tougues has been preserved by the deep waters of Lake Geneva, which have acted as a protective shell for three millennia. Wooden piles, tools, ceramics and organic remains have benefited from remarkable anaerobic conservation, offering researchers a window onto the daily lives of Final Bronze Age populations. The setting is worthy of the story. Lake Geneva, the second largest lake in Western Europe, unfurls its waters here, bordered by the Pre-Alps and the peaks of the Chablais region. Chens-sur-Léman, a small village in Haute-Savoie nestling between Thonon-les-Bains and Geneva, offers a serene view from its shores over this watery space that was, three thousand years ago, a crossroads for trade and intense community life. For lovers of underwater archaeology, experienced divers and prehistory enthusiasts, the Port de Tougues is an extraordinary experience. The site is managed with the rigour required to protect a listed historic monument: any intervention is strictly controlled to preserve the integrity of this irreplaceable heritage. Regional museums, in particular the Musée du Chablais in Thonon-les-Bains, preserve and exhibit some of the archaeological finds from the excavations, giving the general public a close-up view of this sunken lake civilisation.
Architecture
The Port de Tougues belongs to the architectural type of palafittes, or lake dwellings on stilts, characteristic of the Neolithic and Metal Age cultures of the Alps. The basic structure rests on rows of wooden piles - mainly oak and ash, species prized for their resistance to humidity - driven vertically into the sediment of the lake bed. These piles, spaced a few dozen centimetres apart to a few metres depending on the area of the platform, supported a horizontal deck on which the living quarters were built. The walls of these huts were probably built of clay-coated wattle and daub, with roofs made of plant materials such as reeds, thatch or wooden shingles. The spatial organisation of the site reflects the functional needs of a self-sufficient lakeside community: living quarters, food storage areas, bronze-working workshops and areas dedicated to fishing and mooring boats. The presence of metallurgical activity is suggested by fragments of crucibles and casting waste found during the excavations, confirming that the village did not simply import bronze objects, but also produced some of them itself. Now submerged to a depth of between two and six metres depending on the sector, the entire site covers an area estimated at several thousand square metres, the precise configuration of which is gradually being reconstructed by underwater mapping campaigns.
