The upper Moosalb valley is also called the Hammertal ("hammer mill valley") on account of the many witnesses, in the form of ruined buildings and structures, to the iron smelting and working industries of the 18th and 19th centuries.

Before it transferred to the ownership of the Klug family in 1842, whose descendants still run it today, it was called the Wilensteiner Mühle.

The present day Wilenstein Castle Youth Hostel (Jugendheim Burg Wilenstein) is home to a rural educational home (Schullandheim), school and youth groups.

The associated park (Schlosspark) was originally laid out along strict geometric lines in the Versailles style and was considerably larger than it is today.

The structure, built by driving the tunnel simultaneously from both ends, as in classical antiquity, provided the municipality with drinking water until 1965.
