In the Middle Ages, the place called “Laplet, was a peeled hill away from the village. The inhabitants feared this place called the “Mont d'Alle”, because it was said to be the place of the witches' sabbath.

 

The Ardoisière "Laplet" is a former slate extraction factory which has not been in operation since the beginning of the 20th century.
