The United States Department of War established eight European burial grounds for World War I. The ABMC's first program was landscaping and erecting non-sectarian chapels at each of the eight sites, constructing 11 separate monuments and two tablets at other sites in Europe, and constructing the Allied Expeditionary Forces World War I Memorial in Washington, D.C. For those buried who could not be identified during World War I, a percentage were commemorated by Star of David markers, rather than a cross; this practice was not continued for those who could not be identified during World War II.
