Loggerhead Key Lighthouse, Florida
On August 18, 1856 Congress appropriated $35,000 to build a First Order Light Station on Loggerhead Key in the Dry Tortugas. The key is only 1 mile long and 700 yards wide. The tower was supported by a grillage of cross-laid timbers as a foundation to prevent its sinking into the sand and would reach 150 feet in height. 203 granite steps were installed into the tower walls leading to the lantern.
