Hot Springs National Park is an American national park in central Garland County, Arkansas, adjacent to the city of Hot Springs, the county seat. Hot Springs Reservation was initially created by an act of the United States Congress on April 20, 1832, to be preserved for future recreation. Established before the concept of a national park existed, it was the first time that land had been set aside by the federal government to preserve its use as an area for recreation. The hot spring water has been popularly believed for centuries to possess medicinal properties, and was a subject of legend among several Native American tribes. Following federal protection in 1832, the city developed into a successful spa town. Incorporated January 10, 1851, the city was known in the early 20th century as the home to Major League Baseball spring training, illegal gambling, speakeasies during the Prohibition era, and gangsters such as Al Capone, horse racing at Oaklawn Park, the Army and Navy Hospital, and 42nd President Bill Clinton. The area was established as a national park on March 4, 1921
