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 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 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.

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.

First Hawaiian Center is the second tallest building in the U.S. state of Hawaiʻi and the city of Honolulu, the largest city in the state. It is the world corporate headquarters of First Hawaiian Bank, the oldest and largest bank based in Hawaiʻi. The tower is one of the most well-known buildings in Honolulu, with a striking presence at the center of downtown Honolulu's skyline.

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 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. Connors.
