A reclaimed mining landscape in southern Luxembourg where dry grasslands and rocky habitats thrive on former Minett ore grounds.
Brucherbierg-Lallengerbierg Nature Reserve
Brucherbierg-Lallengerbierg is a protected nature reserve in southern Luxembourg, spanning portions of the communes of Schifflange, Kayl, and Esch-sur-Alzette. The reserve covers roughly 267 hectares of land that was, until the 1970s, an active open-pit mining area where iron ore of the Minett region was extracted. Today the scarred terrain has been gradually reclaimed by nature, transforming the site into a mosaic of rocky slopes, filled valleys, and flattened terraces that host a distinctive community of pioneer plants, dry-grassland species, and animals adapted to stony habitats.
The reserve's identity is closely tied to the industrial heritage of southern Luxembourg. Its landscapes were shaped not only by nature but by decades of ore extraction, leaving behind cliffs, spoil heaps, and engineered terraces that now form the physical template for a recovering dry-meadow ecosystem. Because the open vegetation could otherwise be lost to gradual reforestation, dry grasslands within the reserve are intentionally kept open through traditional sheep grazing, a management approach that also preserves the cultural landscape of the Minett.
As one of the many Zones of National Interest in Luxembourg, Brucherbierg-Lallengerbierg illustrates how former industrial land can be repurposed for biodiversity conservation. The site offers a distinctive combination of geological exposure, ecological succession, and active land management that has made it a recognized component of Luxembourg's network of protected natural areas.
