Tucked away in downtown Honolulu stands a magnificent piece of American history that most people don't know exists: Iolani Palace, the only official royal residence in the United States. While castles and mansion museums dot the American landscape, this is the real deal—an actual palace built for and occupied by monarchs.

King Kalākaua commissioned the construction of ʻIolani Palace in 1882, and it became home to Hawaii's last reigning monarchs. The king and his sister, Queen Liliʻuokalani, lived there until the overthrow of the Hawaiian monarchy in 1893. For those eleven years, the palace served as the beating heart of the Kingdom of Hawaiʻi's political and social life, hosting grand balls, diplomatic receptions, and the everyday business of running a sovereign nation.

More Advanced Than the White House

Here's what makes ʻIolani Palace even more remarkable: when it was built, it was more technologically advanced than the White House. The palace had electric lights, indoor plumbing, and telephones before the president's residence in Washington D.C. King Kalākaua was a forward-thinking ruler who embraced innovation, and his palace reflected that vision.

The architecture itself is one-of-a-kind. ʻIolani Palace is the only building in the world constructed in the American Florentine style—a unique blend of Italian Renaissance design adapted for Hawaii's tropical climate and American sensibilities.

What Happened to Hawaii's Monarchy?

The palace's story takes a dark turn in 1893. American businessmen and sugar plantation owners, backed by U.S. Marines, overthrew Queen Liliʻuokalani and ended the Hawaiian Kingdom. The queen was actually imprisoned in the palace—in her own bedroom—for eight months following a failed counter-revolution attempt in 1895.

After the overthrow, the palace served as the capitol building for the provisional government, the Republic of Hawaii, the Territory of Hawaii, and eventually the State of Hawaii until 1969. Government offices filled the ornate rooms where royalty once lived.

A Palace Restored

In 1978, after meticulous restoration work, ʻIolani Palace opened to the public as a museum. Today, visitors can tour the Throne Room, the State Dining Room, and the private quarters of Hawaiian royalty. Many of the original furnishings have been recovered and returned, including the coronation crown and the palace's original chandeliers.

Walking through ʻIolani Palace is walking through a unique chapter of American history—one where the United States wasn't always a republic, where monarchs ruled on American soil, and where a sovereign Pacific nation briefly flourished before being absorbed into the growing American empire.

So yes, technically there are other buildings in America with "palace" in their names—the Governor's Palace in Colonial Williamsburg, Tryon Palace in North Carolina. But those housed British colonial governors, not monarchs. Only ʻIolani Palace can claim to be a true royal palace, making Honolulu the only place in America where royalty actually reigned.
