The LZ 120 and LZ 121 were not allowed to enter service as the Allies had forbidden Germany to make any more Zeppelins at the end of 1919. The German government had hoped that it was only a temporary measure, so the Spa Conference of 1920 was held to address the issue in July 1920 at Spa, Belgium. The Commission Chairman General E. A. Masterman decided on 9August 1920 that the two airships be given to France and Italy as war reparations. The two ships were confiscated under protest by the German government. LZ 121 was awarded to France, which in May 1921 constructed an airship hangar for the zeppelin in Saint-Cyr-l'École at Versailles.
