After the Civil War, efforts to preserve Civil War sites and remember fallen soldiers at Andersonville were led by the Ladies of the Grand Army of the Republic and the Women's Relief Corps. They encouraged states to place monuments recognizing those who died in Camp Sumter Military Prison, and they brought large groups to Andersonville National Cemetery to decorate soldiers' graves with flowers. By the early 1900s, thousands traveled all day by train to Andersonville each year to pay tribute to the soldiers who suffered and died there. The John A. Logan Circle of the Ladies of the Grand Army of the Republic built the Grand Army Memorial Hall or Chapel to shelter weary travelers, and when it was dedicated on Memorial Day in 1908, it became a place to honor soldiers buried in the cemetery. In 1936, the U.S. Army and the Civilian Conservation Corps remodeled the building by covering its granite-like cement blocks with bricks and replacing its flat roof with a gabled one. Updated again in 1960, the structure standing today conceals remnants of the Chapel, itself a faded but treasured memory.
