Origin and history

The Pradelles-Cabardès coolers, located in the department of Aude in the Occitanie region, are semi-entered pits built in the 19th century. They were built to exploit local climatic conditions, 830 metres above sea level at the foot of the Nore Woodpecker, to produce and market natural ice. This trade, initiated around 1849 by Pierre Piquemol, developed rapidly with the construction of five other coolers by his son in 1859, becoming a major economic activity for the village.

Ice was produced by staining winter snow in cylindrical pits 8 to 10 metres in diameter, covered with beech leaves for insulation. The ice loaves, weighing 50 kg, were then transported by carts to the surrounding plains, serving cities such as Carcassonne, Narbonne, Mazamet, and even Toulouse or Bordeaux thanks to the railway. This trade declined in the early 20th century with the advent of artificial ice and the First World War, which requisitioned men and horses, ending this industry in 1927.

The Pradelles-Cabardes coolers, numbering about a dozen, were ingenious structures: a six-metre deep masonry well, topped by a slate roof supported by stone arches and a wooden frame. They included doors for filling and draining, as well as a drainage system for cast iron water. These buildings, which were listed as historic monuments in 1986, reflect a time when natural ice was a valuable and lucrative resource.

The first documents relating to the marketing of ice in the region date back to 1659, when the king authorized by letters patent the construction of coolers in Languedoc. This royal monopoly, initially run by farmers-general, declined in the face of competition from the village ice-makers authorized from 1709. The activity started again around 1850 in the form of independent enterprises, before disappearing permanently with the industrialisation of ice production.

Today, a hiking tour allows you to discover several of these coolers, located near the village and Lake Pradelles-Cabardès. These vestiges illustrate an unknown page of rural industrial heritage, where human ingenuity was able to use natural resources to meet growing ice demand, before technical progress made this activity obsolete.
