Flower Park, named for its flower beds, was once faithfully maintained by residents of Sulphur. By 1935 it had been redesigned into a pedestrian park, and the Lincoln Bridge became its entrance. The Civilian Conservation Corps built new features that included curving trails, reflecting pools, rock dams, cascades, and a serpentine stream, reminiscent of an “English Romantic Landscape.”

In the 1930s, a stream and pools were created in Flower Park to use the sulphur water for health and beauty treatments. Visitors applied the sulphur-rich, black mud on their faces and bodies, hoping to cure their ills.
