Sand Island (Hawaii)

Honolulu Harbor, also called Kulolia and Ke Awa O Kou and the Port of Honolulu , is the principal seaport of Honolulu and the State of Hawaiʻi in the United States. From the harbor, the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oahu. It includes Matson, Inc. harbors on Sand Island.

In September 2013, 1,400 tons of molasses spilled into Honolulu Harbor. The spill was discovered on 9 September 2013. It was caused by a faulty pipe, for which the shipping company Matson Navigation Co. took responsibility. Molasses is an unregulated product, and neither Matson nor government officials had a contingency plan to respond to a molasses spill. Natural currents and weather were expected to eventually dilute and flush the molasses out of the harbor and a nearby lagoon.Divers in the harbor area reported that all sea life in the area were killed by the molasses, which instantly sank to the bottom of the harbor and caused widespread deoxygenation. Members of various coral species were injured or killed, and more than 26,000 fish and members of other marine species suffocated and died.The Hawaiian Commercial & Sugar on Maui produces molasses from fresh sugar cane, and ships it to the mainland to be processed and sold. Matson had been transporting molasses from Honolulu Harbor for 30 years and at the time was shipping it about once a week.

The Aloha Tower is a retired lighthouse that is considered one of the landmarks of the state of Hawaii in the United States. Opened on September 11, 1926, at a then astronomical cost of $160,000, the Aloha Tower is located at Pier 9 of Honolulu Harbor. It has been, and continues to be, a guiding beacon welcoming vessels to the City and County of Honolulu. Just as the Statue of Liberty greeted hundreds of thousands of immigrants each year to New York City, the Aloha Tower greeted hundreds of thousands of immigrants to Honolulu. At 10 stories and 184 feet (56 m) of height topped with 40 feet (12 m) of flag mast, for four decades the Aloha Tower was the tallest structure in Hawaii. It was built in the Hawaiian Gothic architectural style.

The 1999 Honolulu shootings or the Xerox murders were an incident of mass murder that occurred on November 2, 1999, in a Xerox Corporation building in Honolulu, Hawaii, United States. Service technician Byran Koji Uyesugi shot at eight people; wounding seven fatally (six co-workers and his supervisor). This was the worst mass shooting in the history of Hawaii.

The Aloha Tower Marketplace is a waterfront shopping center in Honolulu, Hawaiʻi. Located at the Honolulu Harbor, the Aloha Tower Marketplace includes several national historic landmarks including the Aloha Tower, Falls of Clyde and Hawaiʻi Maritime Center.

The Hawai`i Maritime Center was the principal maritime museum in the State of Hawai`i from 1988 until it closed in 2009. Located at Pier 7 of Honolulu Harbor east of Aloha Tower, the center was a campus of the Princess Bernice Pauahi Bishop Museum. The Hawai`i Maritime Center was built on what once was the private boathouse of King David Kalakaua and was home to the only four-masted, full-rigged ship in the world called the Falls of Clyde. The Falls of Clyde was built in 1878 for the oil industry and is a National Historic Landmark. Also docked at the Hawai`i Maritime Center was the voyaging canoe Hokule`a, a scientific research vessel of great importance to native Hawaiian culture. Due to prevailing economic conditions, the Hawai'i Maritime Center was closed to the public effective May 1, 2009. In December 2017, the Bishop Museum transferred its lease between the Maritime Center and the State of Hawaii to a third party, and ceased operating the Center. Plans for its future are unknown.

Falls of Clyde is the last surviving iron-hulled, four-masted full-rigged ship, and the only remaining sail-driven oil tanker. Designated a U.S. National Historic Landmark in 1989, she is now a museum ship in Honolulu, but her condition has deteriorated. She is currently not open to the public. In September 2008, ownership was transferred to a new nonprofit organization, the Friends of Falls of Clyde. Efforts to raise $1.5 million to get the ship into drydock did not succeed. In November 2021 HDOT accepted a bid from Save Falls of Clyde – International (FOCI) to transport the ship to Scotland for restoration.

The Kakaʻako Pumping Station in Honolulu, Hawaii was designed by architect Oliver G. Traphagen in the Richardsonian Romanesque style. He also designed many such bold stone public works buildings in Duluth, Minnesota. Built in 1900, the pumping station features large arched windows, exterior walls of local lava rock, roofs of green tile, and a smokestack 76 feet tall. It was the first sewerage pumping station in Honolulu, Hawaii, designed to address the serious sanitation problems of the rapidly growing city. It is located on an acre of land between the Kewalo Basin and Downtown Honolulu, at Ala Moana Boulevard and Keawe Street. The Ala Moana Pumping Station took over its functions in 1940, and it has remained vacant for many years. Now under the jurisdiction of the Hawaii Community Development Authority, it is slowly being restored by the nonprofit Hawaii Architectural Foundation.Oliver G. Traphagen also designed the "bright and airy" Moana Hotel on Waikiki Beach.

The C. Brewer Building at 827 Fort Street in Honolulu, Hawaiʻi was built in 1930 to be the headquarters of C. Brewer & Co., the smallest of Hawaiʻi's Big Five corporations. The intimate, almost residential design was begun by Bertram Goodhue and completed by Hardie Phillip. The building was added to the National Register of Historic Places on 2 April 1980. Built of reinforced concrete in a Mediterranean Revival style, with cut sandstone and stucco and plaster finish, a walled garden, and second-floor balconies, it also features a tiled, double-pitched "Dickey roof" with wide eaves to protect against sun and rain. The modest decorations symbolized the business of the C. Brewer Company: wrought iron railings represent sugar cane, and light fixtures were designed to resemble of sugar cubes.After closing down the sugar business and diversifying into other agricultural products and spinning off its real-estate business, the company moved to Hilo, Hawaii on the Big Island of Hawaii in 1998. The building now houses the statewide headquarters of the Hawaii Community Foundation which moved into the building in 2010.

Chinatown station is a planned Honolulu Rail Transit station, serving the Chinatown neighborhood in Honolulu, Hawaii. It is part of the fourth HART segment, scheduled to open in 2031.The Hawaiian Station Name Working Group proposed Hawaiian names for the twelve rail stations on the eastern end of the rail system (stations in the Airport and City Center segments) in April 2019. The proposed name for this station, Holau (alternatively, Hōlau or Ho‘olau), means "many assembled" and is a modern name for a market.

The Dillingham Transportation Building was built in 1929 for Walter F. Dillingham of Honolulu, Hawaiʻi, who founded the Hawaiian Dredging Company (later Dillingham Construction) and ran the Oahu Railway and Land Company founded by his father, Benjamin Franklin Dillingham. The building was designed in an Italian Renaissance Revival by architect Lincoln Rogers of Los Angeles, who also designed the Hawaii State Art Museum (1928). It was added to the National Register of Historic Places in 1979 and restored by Architects Hawaiʻi Ltd. in 1980.
