The Champenay quarry

The Champenay quarry extracts and processes this quartzite sandstone—which boasts exceptional hardness and low porosity—in its workshops. Quarried for centuries, Champenay’s pink sandstone, also known as “Princes’ Sandstone,” is the hardest sandstone in Alsace. The elegance of this natural stone—the only one that can be polished—contributes to its reputation among the greatest contemporary architects…Visible from the outside, but not open to the public.
