Vielsalm is set to continue quarrying its own grindstone for at least another hundred years to come. The grindstone is extracted from a geological stratum that is 480 million years old. You can find out how unique that grindstone is at the Musée du Coticule (the Grindstone Museum) which is located in a green oasis behind the village square of Salmchâteau. If you are looking to sharpen your kitchen knives at home, authentic whetstones can be bought from the museum shop.

Open from early April through late October.
