Diamond Head Lighthouse
In 1825, British sailors ascended the crater and found hard, clear calcite crystals among the black rocks. Mistaking them for diamonds, the sailors named the crater Diamond Head. One of the Hawaiian names for Diamond Head is “leahi”, meaning “wreath of fire.” This name reflects the ancient Hawaiian practice of lighting a fire on the crest of the volcano to guide canoe fleets back to the island.
The first lighthouse on this site was built in 1899. It was rebuilt in 1917 when cracks developed in the earlier structure. The Diamond Head Lighthouse still uses the original Fresnell Lens. The flash of a modern 1000-watt electric bulb is focused by the lens, so it can be seen more than 18 miles out to sea.
The Lighthouse Service was combined with the Coast Guard in 1939. Since then, the Coast Guard has been responsible for the maintenance of lighthouses, buoys, and other aids to
navigation throughout the United States.
The lighthouse keeper’s dwelling, built in 1921, now serves as the
quarters of the Commander, Fourteenth Coast Guard District.
