Vivier maritime de la Gaillarde, Ancient fish pond and archaeological site in Roquebrune-sur-Argens, France.

The Vivier maritime de la Gaillarde is a Roman fish pond in Roquebrune-sur-Argens with three masonry basins carved into the rock. These basins sit beneath the water surface and are separated from each other by stone walls.

The vivier is classified as a monument historique by decree of 23 May 1939. It was not a pleasure pond or a fish store for a villa's owners, but a workshop basin for keeping fish fresh to make garum; a tank for storing this sauce stands in the adjoining property. The nearest Roman villa lies about 500 m away in the vallon de la Gaillarde, likely because the pond smelled strongly.

The name Gaillarde refers to the cove where the pond sits, in the Issambres district of Roquebrune-sur-Argens. The basins were not ornamental: they held live fish for making garum, a fermented fish sauce compared to Asian nuoc-mâm. The neighbouring property preserves a cistern used to store that sauce, and the smell explains why the pond stood about 500 m from the nearest villa, in the Gaillarde valley.

The site is near bus line 876 connecting Saint-Tropez and Saint-Raphaël, with a stop near Beaumont. The best time to visit is at low tide, when the basins become more visible.

The cistern in the adjoining property stored the garum made with fish kept in these basins, not fresh water. The pond stood about 500 m from the nearest Roman villa, in the Gaillarde valley, likely because of the smell of fermenting fish sauce.
