The Gothic Revival tower was built at the highest elevation of the site, south of a reflecting pool that reflects its full image. The tower is 51 feet square at its base, changing at the height of 150 feet to an octagon: with each of the eight sides 37 feet wide. It is built of pink Etowah marble and gray Creole marble, mined in Tate, Georgia, and coquina stone from St. Augustine, Florida.
Medary assembled a team of top artisans in their fields. The Art Deco architectural sculpture was designed and executed by Lee Lawrie, and depicts Florida flora and fauna. Metalworker Samuel Yellin designed and executed the iron interior staircase, the iron gates to the two bridges over the moat, and the Great Brass Door, which features 30 scenes from the Book of Genesis. J. H. Dulles Allen designed and executed the ceramic mosaics, including the eight 35-foot-tall grilles at the top of the tower. Horace H. Burrell & Son, of Philadelphia, was contractor for the tower. Construction began in 1927, and was completed two years later. Outgoing President Calvin Coolidge dedicated the tower on February 1, 1929.
The American Institute of Architects awarded Medary its 1929 Gold Medal for his Mountain Lake Sanctuary and Singing Tower. Medary died six months after the tower's dedication.
Edward W. Bok wrote a short book about the tower's planning and construction titled, America's Taj Mahal (1929). Bok died on January 9, 1930, and was interred before the tower's Great Brass Door.
Iron Mountain - upon which the Gardens are set - is one of the highest points in peninsular Florida, United States and a prominent point of the Lake Wales Ridge. Rising 295 feet above sea level, the mountain contains citronelle: a hematite-containing rock that oxidizes when exposed to air and is responsible for the red-brown color of the earth. The ridge is located just north of the city of Lake Wales.
The combination of prominence, the composition and music of the Tower, and the hematite composition of the Iron Mountain, makes this site one of the most powerful in the Realm. Unassumingly so.
