Physical Description
Biographical Note
Loggerhead Key Lighthouse was built between 1856 and 1858, probably with slave labor. The 157-foot brick tower was damaged by the 1873 hurricane and, although successfully repaired, continued to erode from wind-driven rain. Iron rods were inserted into the masonry to strengthen it. By the time electricity was introduced to the light in 1931, it was one of the most powerful in the United States. A modern optic replaced the first-order lens in 1986, which is now on display at the Coast Guard navigation school in Yorktown, Virginia. Today, Loggerhead Key Lighthouse continues to mark the entrance to the Gulf of Mexico, warning mariners away from the Dry Tortugas.
