In 1919, Congress established the national charter for the American Legion to honor all veterans of the Great War.  Contra Costa County administered a California state bond to build a veterans memorial hall in each county town with an American Legion Post.  The Danville building was erected and was dedicated on April 2, 1925.  In 2008, the building was remodeled, doubling the space.  The building continues to house American Legion Post 246, VFW Post 75, and Viet Nam Veterans of Diablo Valley and welcomes Marine Corps Detachment 942, the Military Order of World Wars, and supporting auxiliary organizations.
