Where is Iolani Palace located?

Iolani Palace is located on the island of Oahu, specifically in the capital city of Honolulu. This site holds significant historical importance as it was the official residence of the Hawaiian monarchs, including King Kalakaua and Queen Liliuokalani, and represents the last royal palace in the United States. The palace is not only a prime example of American Florentine architecture but also serves as a museum that showcases the rich history and culture of Hawaii.

The other islands mentioned—Hawaii Island, Maui, and Kauai—are not the correct locations for Iolani Palace. Each of these islands has its own unique attractions and historical sites, but they do not include the royal heritage embodied by Iolani Palace in Oahu.
