The history of the Sanguinet Lake


The Sanguinet and Cazaux Lake is one of the biggest lakes in the Landes. It is situated along the Aquitaine coastline, in the department of Gironde and the Landes, from Cazaux village to the La Teste de Buch municipality, until the east of Sanguinet and the south of Biscarosse.

It was formed by the accumulation of waters coming from the prairie in the Landes, in particular thanks to the Gourgue, a river where the old village Losa was established before disappearing under the waters.

The Sanguinet Lake has plenty of wonders and histories.


From the 70’s, the site of Sanguinet has been explored little by little and meticulously

measured. The divers of CRESS (Research and Scientific Studies Centre of Sanguinet) has identified several sites of the Iron Age in the former bed of the river Gourgue. They have discovered 35 pirogues (two of them are in the museum) and numerous very valuable vestiges.

Some pieces of pottery, bronze axes, flints and bracelets were found in the lake in 2010 at depths ranging from 14 to 16 metres. They are from the Neolithic periods.
