After the fall of the Kingdom of Hawaii in 1895, the palace building was used to imprison Queen Liliuokalani, the last reigning monarch of the Kingdom of Hawaii whom the government was overthrown. The palace was then used as the capitol building for the territory when Hawaii was State of Hawaii to the United States of America in 1959.
The palace was restored in 1969 to become the museum of the Kingdom of Hawaii era. Guided tours and self-guided tours are conducted daily but I missed the time of the tour during my visit. Therefore, I took home only the pictures of the palace building.
