The Fond fountain appears on a map of Talmont in 1706, drawn up by the engineer Claude Masse. It is described as a "fountain or soft well".
In his writings accompanying his maps and plans, Masse mentions this fountain, the only source of fresh water in Talmont. The fountain then appears on the cadastral map of 1831. The pump and the drinking troughs were apparently installed in 1868.
Until the establishment of the water supply, this fountain was the only source of drinking water in the commune, the wells only providing brackish water.
The pumping system, initially a balance, later included a wheel. Wooden pipes distributed the water to the stamps. At the top of the pump, another pipe allowed the barrels to be filled in carts.
The fountain is located in front of the Fond lodge, at the end of Rue des Porteaux, below the Caillaud hill.
The fountain itself is topped with a stone aedicule, with a metal mechanism. It is surrounded by seven monolithic stone drinking troughs or "timbres".
