La Roche à l'Appel

The name "La Roche à l’Appel" likely derives from a corruption of a local term. "Pèle" (the shovel) is the word used locally to refer to the tool used to pack the charcoal produced at the "place de faulde" (place of fire). This spot, where the oven was built to burn the wood, was located near the geological site. "La Roche à l’Appel" is therefore derived from "Roche à la Pèle." The site of La Roche à l’Appel was classified by Royal Decree of March 16, 1965.

La Roche à l'Appel resembles a chaotic accumulation of enormous Fépin pudding stones. The surrounding forests are very diverse: oak, beech, and coniferous. In some places, along the streams that cut through the slope, peatlands of botanical interest run along them. The small world of mosses and liverworts is remarkably rich and diverse. The entomological fauna, especially beetles, is also represented by many species, some of which are very rare elsewhere in the country.
