This cross was built to commemorate all dead soldiers of all nationalities who died at the battle of the famous bridge of Remagen in March 1945.
I didn't get a clear shot of the remaining pillars but you can find more information and pictures of the bridge here: http://de.wikipedia.org/wiki/Die_Br%C3%BCcke_von_Remagen
May peace prevail on earth.
