 In the Steinalb valley within Niederalben's limits once stood a few mills, but in 1938 they suddenly found themselves within the Baumholder Troop Drilling Ground, and have since fallen into disrepair.The only nearby mill that is still running stands near Niederalben on the Steinalb, but over on the Steinalb's right bank and thus on the far side of the old Bavarian-Prussian border, within Rathsweiler’s limits.Until the Second World War, the predominant economic structure was agricultural.
