 Just above the village is the edge of the Baumholder Troop Drilling Ground.Unterjeckenbach's “twin”, Oberjeckenbach, once lay about a kilometre away, but it was swallowed up in 1933 when the troop drilling ground was laid out by the Nazis.The municipal area measures 315 ha, of which 24 ha is wooded and 6 ha is given over to habitation.
