The most spectacular fact about this cave is the low temperature of about 0° Celcius. It is caused by the form of the cave, a single room with a large opening on the top. The same effect occurs, everybody knows from the supermarket: as cold air has a higher density (is heavier) than warm air, it has no possibility to escape from the refrigerator, if there is just an opening at the top.
In winter cold air flows into the cave, in summer there is no possibility for the cold air to escape or for warm air to enter. Many caves contain ice flowstones in winter, but it is very rare if they stay all the year.
This is the only ice cave of its type in France. Inhabited in prehistoric times it was first visited in the 16th century by Boissotnot in 1584 by Gollut in 1592 and Boissot in 1686. Later it was visited by E A Martel and Fornier who studied the temperature, and the glacial phenomena. The cave has also attracted the attention of scientists and poets, who have come to marvel at the rich decorations.
At the entrance there is the Maison des Mineraux - a Museum of Minerals with samples of over 500 minerals from all over the world. Admission free.
