In the Müllerthal there are countless caves and rock overhangs where people have been seeking shelter since time immemorial. The Luxembourg sandstone is not only the largest water reservoir in the country but also offered a protective home for prehistoric cultures or for people who operated charcoal kilns.
Resistance groups also hid here in the caves and crevices.
Am Mëllerdall ginn et eng Onmass vu Grotten a Fielsiwwerhäng, wou d'Leit zanter Zäiten en Ënnerdaach gesicht hun. De Lëtzebuerger Sandsteen ass net nëmmen dee gréisste Waasserreservoir am Land, mee bitt och e Schutzraum fir prähistoresch Kulturen oder fir Leit, déi Kuelemeiler bedriwwen hun.
Resistenzgruppen hunn sech och hei an de Höhlen a Spalten verstoppt.
