How a lavogne works is very easy to understand, just imagine a gigantic upturned umbrella that collects rainwater!At the beginning there was a natural pond with an impervious clay soil. This small pond was a real boon for people who quickly set these watering sources up as they were so critical on the causses where water seeps into the cracked limestone. To start with, they tiled the inside of the pond and finished off the work by laying paving stones around the edge of the pond to preserve the water quality and prevent gullying due to the large flocks trampling the soil when the sheep come to drink.The pond tiling was made either with lauzes, flat stones or with paving stones laid one after the other.Once completed, this gigantic upturned umbrella would provide a great variety of animals with a welcoming habitat, just look down over a lavogne and see how it swarms and buzzes with life, what a frenzy of activity!
