The troughs are containers, generally made of mono-bloc of stone, serving as feeder. Indeed, these troughs, long and hollow, were meant to give food and / or drink to the farm animals, especially the pigs.
They remind us of our rural past and needs. They also reflect the skills of our peers stone-masons, often anonymous, who have perpetuated our popular art over the centuries.
Now these old elements can be used for landscaping your outdoors : flowerpots, planters, small fountains ... They can also be turned into sinks or water-bassins.
