The Lincoln Tomb is the final resting place of the 16th President of the United States, Abraham Lincoln, his wife, Mary Todd Lincoln, and three of their four sons. It is located in Oak Ridge Cemetery in Springfield, Illinois. At the close of the events marking Lincoln's death, his body was placed in a nearby receiving tomb and later in the state tomb. The mausoleum is owned and administered by the State of Illinois as Lincoln Tomb State Historic Site. It was designated one of the first National Historic Landmarks in 1960, and thus became one of the first sites listed on the National Register of Historic Places in 1966, when that designation was created.
