A natural ravine was developed into Ravine Gardens in the 1930s by the City of Palatka and the Federal Government, and the suspension bridges and amphitheater built then were later placed on the National Register of Historic Places. The Gardens contain two pedestrian suspension bridges, replacement structures for the originals, each spanning about 120 feet. They were built with concrete bases at either end, limerock anchors for steel cables, and paired reinforced concrete masts at the ends. The bridges crossed land rather than water, as Whitewater Branch below them was channeled underground with limerock and concrete dams, culverts, and a spillway, and a 40 to 50 foot area beneath each bridge was filled with soil and plantings. The bridges have been reconstructed, and only the concrete masts are original. The amphitheater was developed in 1939 at the junction of the branches in response to the needs of the Miss Azalea Pageant and remains basically unchanged. Across the Gardens loop road, its seating area rises uphill in eight arced terraces marked by low limerock walls, while the terraced stage has limerock walls at three levels and stairs at the center of both sides, with a U-shaped walkway on the lower level.
