Jacksonville's beloved Treaty Oak is a Southern Live Oak, at least two centuries old, rising over 70 feet with a 25-foot trunk circumference. In the early 1900s, when it was known as Giant Oak, it was often decorated with electric lights and served as the main attraction of Dixieland Amusement Park, where Babe Ruth once played baseball and John Phillip Sousa gave a concert, while also providing shady picnic grounds for families and a backdrop for silent films produced nearby in 1910. After the lights, music, and movie glamour faded at the end of World War I, the tree and its site remained cherished in Jacksonville. Its popular name came from a journalist seeking to save it from developers by publishing a false story that a treaty between Indians and early settlers had been signed beneath its limbs. The oak's preservation was ultimately secured through the dedication and generosity of the Garden Club of Jacksonville and other civic organizations, which persuaded city officials not to allow nearby construction. In 1964, at the Garden Club's request, Jessie Ball duPont bought the remaining seven lots around the tree and donated them to the city for use only as a public park, preventing future development. First called Treaty Oak Park, the site was later renamed Jessie Ball duPont Park in honor of her generosity and love of nature.
