Pensacola Light, Florida.
Exhibited January 1, 1859. the first-order revolving light's beam was 160 feet above the ground and 210 feet above sea level.
During the Civil War the confederates bomabarded the tower with solid shot and put the light out of operation. In 1863, the installation of the fourth-order lens relighted the tower, and this lens continued in service until 1869, when a first-order lens was re-established in the tower.
