Created mostly with land granted by Colonel Lemuel Grant, the "Father of Atlanta," Grant Park is the oldest surviving park in the city. Its landscape was part of the defensive line against Union forces in the Civil War, and the breastworks of Fort Walker remain as evidence of the Confederacy's defeat. The Cyclorama, a circular building filled with the world's largest painting, tells the story of the battle. The park's other main attraction is Zoo Atlanta, one of the only places in the country that you can see a set of giant pandas.
