Honolulu Harbor, also called Kulolia and Ke Awa O Kou, is the principal seaport of Honolulu and the State of Hawaiʻi in the United States. It is from Honolulu Harbor, that the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oʻahu.
Honolulu Harbor is administered by the Hawaiʻi State Department of Transportation Harbors Division. Honolulu Harbor handles over 11 million tons of cargo annually. The services that the harbor provides are crucial as Hawaiʻi imports over eighty percent of its required goods.
Early history 
Archaeological surveys conclude that the area around Honolulu Harbor was bustling with human activity prior to 1100. The first European vessel to enter Honolulu Harbor was a long-boat from the H.M.S. King George. The boat rowed into the harbor on December 12, 1786, commanded by a Mr.Hayward and piloted by Towanooha. In 1794 the HMS Butterworth, a British ship commanded by Captain William Brown, entered the same harbor by "warping" in. Sailors aboard the ship dubbed the harbor Brown's Harbor to their captain's dismay. Captain Brown insisted that the harbor be called Fair Haven. Fair Haven is synonymous in meaning to the Hawaiian name for the region, Honolulu.
In 1850, Kamehameha III declared Honolulu to be the official capital of the Kingdom of Hawaiʻi. With the proclamation came a series of investments to further develop the harbor to accommodate more vessels. Honolulu Harbor quickly became the chief port of call for the trans-Pacific sandalwood, fur and whaling industries. Foreign vessels that docked at Honolulu Harbor poured vast amounts of wealth into the kingdom's coffers and provided for the well-being of native Hawaiians.
Aloha Tower 
On September 11, 1926, after five years of construction, the world-famous Aloha Tower was officially dedicated at Pier 9 of Honolulu Harbor. The tallest building in Hawaiʻi at that time, the Aloha Tower became a guiding beacon welcoming vessels to Honolulu. Just as the Statue of Liberty greeted thousands of immigrants each year to New York City, the Aloha Tower greeted thousands of immigrants to Honolulu. By the time the Aloha Tower was dedicated, Honolulu was already a popular vacation destination for wealthy American and European families. They traveled on Matson steamers that docked at the Aloha Tower and were greeted by Hawaiian music, hula performers and lei.
When the attack on Pearl Harbor came on December 7, 1941, Coast Guardsmen from the USCGC Taney were ordered to take up defensive positions around Aloha Tower and protect it from being occupied. The Aloha Tower was painted in camouflage so as to disappear at night.
Recent developments 
In 1982, the Hawaiʻi Maritime Center was opened near the Aloha Tower in an old royal pier to present the history of Honolulu Harbor and the relative industries it served. Docked at the royal pier is the Falls of Clyde, a historic shipping vessel. In 2002, the Hawaiʻi Maritime Center became an incorporated institution of the Bishop Museum. In 1994, the Aloha Tower Marketplace opened making Honolulu Harbor the only harbor in the nation to combine a visitor attraction, retail and restaurant outlets, and working commercial harbor facilities at a single location.
