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 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 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 Honolulu Sailor's Home is a non-profit lodge for international merchant seamen. The home was incorporated in May 1855 with a lot obtained by a grant from the Kingdom of Hawaii.

The United States District Court for the District of Hawaii (in case citations, D. Haw.) is the principal trial court of the United States Federal Court System in the state of Hawaii. The court's territorial jurisdiction encompasses the state of Hawaii and the territories of Midway Atoll, Wake Island, Johnston Atoll, Kingman Reef, Palmyra Atoll, Baker Island, Howland Island, and Jarvis Island; it also occasionally handles (jointly with the United States District Court for the District of Columbia and the High Court of American Samoa) federal issues that arise in the territory of American Samoa, which has no local federal court or territorial court. It is located at the Prince Kuhio Federal Building in downtown Honolulu, fronting the Aloha Tower and Honolulu Harbor. The court hears both civil and criminal cases as a court of law and equity. A branch of the district court is the United States Bankruptcy Court which also has chambers in the federal building. The United States Court of Appeals for the Ninth Circuit has appellate jurisdiction over cases coming out of the District of Hawaii (except for patent claims and claims against the U.S. government under the Tucker Act, which are appealed to the Federal Circuit). The United States Attorney for the District of Hawaii represents the United States in all civil and criminal cases within her district. As of January 3, 2022 the United States Attorney is Clare E.

The Honolulu Courthouse, also known as simply the Court House or the Parliament House, and later known as the Old Courthouse, was a two-story building in Downtown Honolulu that served as the meeting location of the Hawaiian Kingdom's Legislature and Supreme Court between 1852 and 1874. It was also the site of the Legislature's election of William Lunalilo and David Kalākaua as king in 1873 and 1874, respectively. A riot that broke out following the election of Kalākaua caused significant damage to the building and its contents. The Legislature and Judiciary moved out of the Honolulu Courthouse in 1874 and the building was subsequently sold to H. Hackfeld and Company (later renamed Amfac), which used the building for office and warehouse space until it was demolished in 1968 to make room for a new office complex.

The Prince Kūhiō Federal Building, formally the Prince Jonah Kūhiō Kalanianaʻole Federal Building and United States Courthouse, is the official seat of the United States federal government and its local branches of various agencies and departments in the state of Hawaiʻi. Its address is 300 Ala Moana Boulevard, Honolulu, Hawaii 96850.The building was completed in 1977 with a total of 929,857 square feet (86,386.5 m2) of working space. It houses the United States District Court for the District of Hawaii, the United States Attorney for the District of Hawaii, the United States Court of Appeals for the Ninth Circuit (Honolulu Division), the offices of Hawaii's U.S. Senators, the offices of Hawaii's U.S. Representatives for Hawaii's 1st congressional district and Hawaii's 2nd congressional district, and branch offices of the United States Secret Service, United States Probation and Pretrial Services System, Department of Homeland Security, United States Department of Justice, Central Intelligence Agency, Federal Bureau of Investigation, Internal Revenue Service, Department of Veterans Affairs, among other entities.The building was named after Prince Jonah Kūhiō Kalanianaʻole, heir to the throne of the overthrown Kingdom of Hawaiʻi, who served as Republican territorial delegate to the United States Congress from 1903 through 1922. It was built on part of the former US Army Fort Armstrong, which was named for Samuel C. Armstrong (1839–1893), son of Hawaiian missionaries. Across Ala Moana Boulevard is the Aloha Tower at the Honolulu harbor. Other parts of Fort Armstrong became a container terminal for military supplies.The Prince Kūhiō Building was constructed to replace the aging Federal Court, Customs House and Post Office building fronting ʻIolani Palace and adjacent to Aliʻiōlani Hale which had been built in 1922 and expanded in 1931. After being mostly vacant, the old building was renovated and put up for sale. The old building was given back to the state of Hawaiʻi and was renamed the King David Kalākaua Building in December 2003.Construction of the Prince Kūhiō Federal Building was not without controversy. The General Services Administration wanted a simple tall office tower, while local architects argued for a building more appropriate to Hawaii. Statutes provided that all buildings between the shoreline and the foot of Punchbowl Crater could not be taller than the Hawaiʻi State Capitol. The federal government, not legally limited by local statutes, defied the statutes and constructed the building as the tallest structure in the path of the capitol building's view of the shoreline. The complex includes ten stories of offices (including a penthouse level), connected by an enclosed bridge to a six-story courthouse building (including basement).The Prince Kūhiō Federal Building was designed by Joseph G.F. Farrell's firm Architects Hawaii. Other government buildings designed by the firm include the capitol building of Palau, which opened in 2006. The building was selected for $121 million of renovations as part of the American Recovery and Reinvestment Act of 2009. The plan is to make the building more efficient by upgrading its mechanical, electrical, fire-safety, and plumbing systems. It had already been cited as an efficient building by the Energy Star program. Traces of asbestos were discovered during the first phase. The second phase of construction was approved in March 2011.

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.

The Stangenwald Building at 119 Merchant Street, in downtown Honolulu, Hawaii was the city's first high-rise office building, with its own law library, and one of the earliest electric elevators in the (then) Territory when it was built in 1901. It was also advertised as "fireproof" because it was built of concrete, stone, brick, and steel, with no wood except in the windows, doors, and furniture, and because it had fireproof vaults and firehoses on every floor. Fireproofing was an important selling point because of the fire that had devastated nearby Chinatown the previous year.) Apart from a few exceptional structures like Aloha Tower (1926) and Honolulu Hale (1929), it remained the tallest building in Honolulu for half a century, until the building boom of the 1950s.Young local architect C.W. Dickey designed it with features of Italianate architecture: arched windows, terra cotta ornaments, and a wide balcony with fine grillwork above the entrance. Every floor had a unique exterior. The interior vestibule and hall were decorated with mosaic tile floors and marble panelling, while the stairways had slate and marble steps. In 1980, another local architect, James K. Tsugawa, completed an award-winning restoration.Dr. Hugo Stangenwald was an Austrian physician and pioneer photographer who arrived in Honolulu in 1853. In 1869, he bought the 5,303-square-foot (492.7 m2) property and built his medical offices there, in partnership with Dr. Gerrit P. Judd next door. Not long before he died in 1899, he leased the land to a group who planned a fine structure to match the quality of the Judd Building (1898) next door, designed by Oliver G. Traphagen, who had just arrived from Duluth, Minnesota.
