ʻIolani Palace is a historic royal palace located in downtown Honolulu, Hawaii. It was the official residence of the Hawaiian monarchs from 1882 until 1893, when the monarchy was overthrown. The palace was built in the American Florentine style and is considered a masterpiece of Hawaiian architecture.

The palace was commissioned by King Kalākaua in 1879 and completed in 1882. It was equipped with the latest technologies of the time, including indoor plumbing, electricity, and a telephone. The palace was also decorated with exquisite furnishings and works of art from around the world.

After the overthrow of the Hawaiian monarchy in 1893, the palace was used as the headquarters of the provisional government, and later as the capitol building for the Territory of Hawaii. In 1962, the palace was restored to its original condition and opened to the public as a museum. Today, visitors can tour the palace and learn about Hawaiian history, culture, and monarchy.
