Diamond Head is the name of a volcanic tuff cone on the Hawaiian island of Oʻahu and known to Hawaiians as Lēʻahi. Its English name was given by British sailors in the 19th century, who mistook calcite crystals embedded in the rock for diamonds. It is located on the coast east of Waikīkī, Honolulu.
Diamond Head is part of the complex of cones, vents, and their associated eruption flows that are collectively known to geologists as the Honolulu Volcanic Series, eruptions from the Koʻolau Volcano that took place long after the volcano formed and had gone dormant.
Volcano - extinct for 150000 years. 990 meters wide and 230 meters tall
1909 - Fort Ruger named after Civil War General Thomas H. Ruger and built in and around Diamond Head Crater, the fort was established by the United States for the purpose of defending the harbor of its newly annexed territory.
Fort Ruger was the site of Battery Harlow, armed with eight 12-inch mortars. The fort's prominent location on Diamond Head made it a natural fire control station, with several posts built into Leahi Peak.
In the event of an enemy landing, the Diamond Head crater was supposed to act as a natural strongpoint for holding the island indefinitely.
