What are two historical sites of Hawaii?

* Pearl Harbor: This historic site is located in Honolulu and is where the Japanese Imperial Navy attacked the United States naval base in 1941, leading to the United States' entry into World War II. The site includes the USS Arizona Memorial, which is built over the sunken battleship Arizona, and other memorials and museums that honor those who served and died during the attack.

* Iolani Palace: This palace was the official royal residence of the Hawaiian Kingdom and is now a museum. It is located in Honolulu and was built in the 1880s for King Kalākaua. The palace is a beautiful example of Hawaiian architecture and houses many artifacts from the Hawaiian Kingdom period.
