The
Third Tybee Lighthouse
In 1768, with the
sea lapping at the foundation of the lighthouse, the Georgia Assembly
authorized a new lighthouse to be built. This time a site well removed
from the sea was chosen and the light was completed in early 1773. The
100 foot tall brick and wood structure was lit with spermaceti candles.
(Spermaceti is a waxy,, white substance from a sperm whale’s skull)..
The lighthouse was ceded to the Federal Government about 1790,, after
Georgia ratified the Constitution and became part of the United States.
The U.S. Lighthouse Establishment then took over the operation of the
lighthouse

A
new lens....
In
1857, a Second Order Fresnel lens was placed in the lighthouse. The
lens greatly increased the effectiveness of the light through the use
of prism.
War!
In
1862, a major portion of the lighthouse was destroyed when Confederate
troops from Fort Pulaski set fire to the tower in order to prevent the
Federal troops from using it to guide their ships into port. Fort Pulaski
stands now, as it was then, to learn more click here
