Before the construction of the washhouse, the washerwomen of Peppange used a small pond in a backwater of the Alzette in the middle of the valley, on the border between the two districts of Peppange and Berchem. In 1894, the municipality of Roeser had the washhouse built with a surrounding wall and roof next to the road leading to Hellange.

Intense red, rugged cliffs rise up next to the cycle path. The color is due to the ore. Really special!
