The Ellergronn nature reserve near Esch-sur-Alzette is a significant part of Luxembourg's Minette region and the UNESCO biosphere. The site encompasses former iron ore mines that were renatured following the cessation of mining activities and now harbor impressive biodiversity. The central hub is the nature conservation center 'Burfelt', located in the restored buildings of the former 'Katzenberg' mine. Here, visitors find exhibitions on the region's flora and fauna as well as its industrial past. The landscape is characterized by beech forests, dry grasslands, and small bodies of water that formed in the former extraction sites. Hiking trails, such as the 'Natura 2000' path, lead through the area and explain the ecological value of these secondary biotopes. Ellergronn serves not only for nature conservation but also as a recreation area for the country's second-largest city and as a venue for education on sustainable development.
