The car park opposite the Wavreille anticline, a geological phenomenon typical of the area, harbours a lime kiln that was still in use during the early 20th century. Quicklime was produced here out of local limestone which is composed mainly of calcium carbonate (CaCo3). The stones were poured into the oven from carts, and then heated to a temperature higher than 900° Celsius. The layers of limestone were alternated with layers of wood coal, and the mixture released carbon monoxide and quicklime. When quicklime is combined with water, it becomes slaked lime.
