Once an active system of mills powered by 8 natural springs, nowadays the site is merely ruins in the forest.

Now just a sign remains to remind visitors that a mill once stood on the site. Situated between Grevenmacher and Machtum, the ruins of the "Mull", as it was named in 1777, lay at a height of 139 metres.

Deisermillen was made up of 4 different mills. At the top, the chalk and oil mills made the water wheel move, which powered the tanbark mill and the mill on Rue de Machtum. The mills didn't just produce flour, but also tannin for leather production.

In December 1964, a landslide destroyed the Deisermillen site. The ground gave way from 300 to 200 metres, taking everything with it.

The manor house built by the Deisermillen owner in the 19th century was also destroyed in the landslide. Today, just two exotic ancient trees are what remain of the impressive gardens that once belonged to the manor house.

The remains now lie in the area belonging to the Kelsbaach Nature Reserve, named after the stream that powered the mills. The 75 hectare site was named a protected area in August 1998 due to its environmental value.

About this series

In this popular series, RTL photographer Domingos Oliveira takes you to hidden places, lesser known locations and buildings with an interesting story.

1) The first instalment captured the last moment of the agricultural centre in Mersch.

2) We then visited Zenningen Zoo, which was closed in the early 80s. 

3) Our third trip took us to Hesperange's eery swimming pool which now looks like the setting for an apocalyptic film.

4) The fourth photo series targeted the veritable ghost town "Cité Syrdall."

5) We also visited the iconic cinema Ariston in Esch, which opened in 1962 and closed in 2016. The cinema's history is an eventful one - from erotic films to youth theatre.

6) In the sixth instalment, we took a trip down memory lane and revisited pictures of Luxembourg City's former "centre Aldringen," an underground parking lot and cultural hub that gave way to Centre Hamilius.

7) The seventh gallery in the series took us to Luxembourg's former police museum.

8) And in the 8th instalment we got to take a look at a cemetery for old fire engines.

9) The 9th gallery visited the Lentilles Terres Rouges site in Esch.

10) The 10th instalment explored the old ArcelorMittal works in Esch and Schifflange.

11) The 11th photo series resulted in fantastic views of Birtrange Castle.
