Lime kiln, located near the caves and used to make lime in the 19th century. Free admission.
The stone (limestone) was quarried from the surrounding area and then transported to the top of the building. Filled with a mixture of limestone and wood (or anthracite), the kiln was then heated to around 1000°. After cooling for a few days, the lime was recovered from the bottom of the kiln. This "quick" lime was then "slaked" with water to be used as a soil improver (in the 19th century). The use of chemical fertilisers led to the disappearance of this method of production.
The lime kiln has been fully restored and the exterior can be viewed all year round.
