In the center of the village of Montdardier, there is a ice house. This half-buried building is 8 meters deep. Formerly, and until the 1920’s, large ice blocks were collected in winter from the lavognes (little ponds where flocks water on the causses) and were stored in the ice house. Straw was placed between each layer of ice : thus it could be kept for months. The enabled the inhabitants of the castle of Montdardier to have ice in order to chill drinks, preserve food and make sorbets (this dessert, invented in Italy in the 18th century, was quickly appreciated by high society).
