 Still belonging today to Sankt Julian’s municipal area is a 327-hectare uninhabited area called the "Schwarzland" ("Blackland") which was incorporated into the Baumholder troop drilling ground in the 1930s when the Nazis established it, and which has now formally been transferred back to the municipality.Over on the Glan’s right bank, the formerly self-administering municipality of Sankt Julian had parts of its municipal area.They bordered on the Lenschbach, which formerly marked the border between lands held by the Waldgraves and those held by the Duchy of Palatinate-Zweibrücken.
