The museum across the country
Kirchberg Arboretum
The woody plant collection of the Kirchberg Arboretum extends over a total area of around 30 hectares, spread across three public parks in the Kirchberg district: Parc Central, Parc Réimerwee and Parc Klosegrënnchen.
Since 1994, trees and shrubs from across Europe and neighbouring regions have been planted here by the Fonds d’urbanisation et d’aménagement du plateau de Kirchberg [Kirchberg Plateau Urbanisation and Development Fund]. The National Museum of Natural History is responsible for the scientific management of the collection, which is continually expanding and now includes around 450 species and varieties.

"Giele Botter" geological trail
Discover the rich geological heritage of Luxembourg’s Minett region as you explore the Giele Botter geosite, a former open cast mine located between Differdange and Pétange.
With its 10 bilingual stations (French/German), the Giele Botter geological trail immerses visitors in the geological history of the famous Minett iron ore. Formed in a tropical sea during the Jurassic period around 177 million years ago, the Minett of Lorraine and Luxembourg represents one of the world’s most important iron ore deposits. Learn about its formation, its geological composition, and the fossils that bear witness to marine life in the Jurassic era
Enjoy a 2–3 hour walk through the lush nature of the Giele Botter–Prënzebierg nature reserve -- perfect for the curious, the passionate, and anyone who loves to explore and connect with the world around them.
Free admission (not suitable for people with reduced mobility).
Start on foot from Fonds de Gras, Parking Titelberg, or the Niederkorn water reservoir.
This trail was developed by the MNHNL in collaboration with the City of Differdange, the Nature and Forest Agency, and the Minett Park Fonds-de-Gras.
Fossil Tour through the City
Take part in an urban geological exploration: a fossil hunt in the city.
The pavements, plinths and façades of Luxembourg City are dotted with fossil remains of long extinct organisms -- silent witnesses of a distant past. Embedded in the natural stones used for buildings, these urban fossils offer a fascinating journey through 350 million years of Earth’s history.
Discover a selection of 14 remarkable fossils on a walk linking the Naturmusée to the central railway station.
A detailed brochure, including information about the fossils, the route and a map, is available free of charge at the MNHNL.
The fossil hunt can be enjoyed all year round.
“De Saturn” – Astronomical trail in Schifflange
Set off on an exploration of our solar system in the heart of the spectacular Minett landscape in southern Luxembourg, at the Lallenger Bierg site in Schifflange. At the same time, discover the local biodiversity of this former open cast mine once operated by ARBED (ArcelorMittal).
Marked with educational panels, this 4-kilometre trail provides information about celestial bodies, from the Sun to the planets, as well as asteroids and comets. The scale of distances, reduced to 1:2 billion, allows you to walk through the entirety of our solar system, while the size of the Sun and planets is reproduced in relief at a 1:1 billion scale. The thirteen educational panels offer images and additional information about these celestial bodies, as well as the ancient mythology behind their names.
Free admission (not suitable for people with reduced mobility). The route, to be completed on foot, starts at the Stade Jean Jacoby in Schifflange and returns to the starting point.
This trail was designed by the Luxembourg National Museum of Natural History (MNHNL), in collaboration with the former Ecological Service of the Municipality of Schifflange, the Schifflange Tourist Office (S.I.T), and the local initiative and management centre CIGL.
"Kofferminn" in Stolzembourg - the historic copper mine
Discover the rich mining heritage of the former copper mine of Stolzembourg: visit the Koffergrouf museum, follow the “Mir ginn op d’Grouf” [Let’s go to the mine] trail on foot, and descend into the mine to explore the remains of historic copper extraction.
Marked by 10 bilingual educational panels (French/German), the geological trail “Mir ginn op d’Grouf” immerses visitors in the geological history of a copper vein and its accompanying mineral, formed during the Cretaceous period at a depth of 3 km. After the erosion of the overlying layers, the vein was exploited for several centuries, although mining was often complicated by water infiltration.
A 2.5 km hike through the Our Nature Park links the museum to the mine. Ideal for lovers of nature, history, geology, and natural and mining heritage.
Free admission
Please note: the trail is not suitable for people with reduced mobility.
Departure on foot from the centre of Stolzembourg.
This trail was developed by the Musée National d’Histoire Naturelle Luxembourg (MNHNL) [Luxembourg National Museum of Natural History], in collaboration with the Stolzembourg Tourist Office and the Our Nature Park.
Antimony Mine of Goesdorf
Dive into the fascinating world of the Goesdorf antimony mine, a geological and historical heritage site unlike any other in Luxembourg.
Explore one of the country’s most remarkable mining sites: the antimony mine geosite of Goesdorf, located on the plateau of the same name in the north of Luxembourg. Here, human history and geological history have been intertwined for more than seven centuries.
The first mining rights were granted in 1354 by Duke Wenceslas I. From that moment on, the extraction of antimony—a malleable metal initially used in medicine and later primarily for the production of printing type—profoundly shaped the village’s history. Although the mine closed permanently in 1938, it yielded remarkable finds over the centuries, including a spectacular 52 kg piece of stibnite, long considered one of the largest ever discovered worldwide.
The site’s mineralogical richness is the result of a complex geological history. The surrounding rocks—ancient Devonian schists (around 400 million years old)—were folded during the Variscan orogeny. Tectonic movements fractured these rocks, allowing hot fluids to circulate and form several generations of minerals. From quartz and pyrite marked by traces of arsenic during the first phase, to impressive stibnite veins (Sb₂S₃) dating from the Permian period (around 300 million years ago), and finally to sulfosalts formed during the Jurassic, the Goesdorf mine stands as a true record of the deep evolution of the Earth’s crust.
The Goesdorf geological trail, approximately 2.5 kilometres long, invites visitors to discover these geological and cultural treasures along a scenic walk. The route leads to the former forge, the remains of extraction areas, and the drainage gallery, revealing traces left by centuries of mining activity. Access is free, although the trail is not suitable for people with reduced mobility. Guided tours for groups can be arranged on request.
