 As a relic of an almost forgotten communication technology, a reconstructed optical telegraph station still stands high over the countryside near Oeynhausen.This is run by the Oeynhausen history club ("Heimatverein"), and guided tours are available to those who wish them.In Nieheim, a kind of cheese is made, "Nieheimer Käse" (Nieheim cheese), a sour milk cheese nowadays made by only one cheesemaker.
