The coastal dune, on which the houses of Saint Girons-Plage and Huchet are built, was created from 1822 onwards, invented by the Ponts et Chaussées engineer Jean-Sebastien Goury. With the help of fences, he obtained piles of sand according to a particular profile that he tried to reproduce over 200 km. The dune thus formed, stabilised by the planting of gourbet, thus protected the young pine trees from the sandy winds, which were intended to fix the interior dunes. From 1850 onwards, the State authorised the establishment of bathing hotels and houses. The future Côte d'Argent (named as such in 1905) was born.
