The Diamond Head Lighthouse is an iconic landmark along the southern coastline of Waikīkī located at the base of the towering conical crater of Diamond Head. The name stuck after sailors in the 1820s believed they had found diamonds in the rocky slopes. These "diamonds" turned out to be simple calcite crystals. In the late 19th century, before the construction of the lighthouse, a watchtower was used to spot ships off the coast. However, during foul weather two ships ran aground on the reef just off of Diamond Head. These incidents sparked a petition to establish a light to guide the increasing number of vessels sailing around the point.

Originally built out of slender iron pipes, the 40-foot framework for the lighthouse was deemed not strong enough to withstand a gale. Thus it was reinforced with coral rock and supports until the early 20th century, when cracks in the structure compromised the lighthouse's integrity. The tower was dismantled and replaced with the modern 50-foot structure, an internal spiral staircase, and keeper's quarters. The light was also converted from oil to modern electricity. Today the quarters and grounds are off-limits to the general public, but the lighthouse can be viewed from the summit of Diamond Head and the Diamond Head Beach Park.
