The Stephen A. Douglas Tomb and Memorial or Stephen Douglas Monument Park is a memorial that includes the tomb of United States Senator Stephen A. Douglas (1813 – 1861). It is located at 636 E. 35th Street in the Bronzeville neighborhood of Chicago, Illinois (part of the city's Douglas community), near the site of the Union Army and prisoner of war Camp Douglas. The land was originally owned by Douglas’ estate but was sold to the state of Illinois, when it became known as “Camp Douglas” serving first as training grounds for Union soldiers during the Civil War, then as a prisoner of war camp.
