This cache takes you to the birthplace of Prince Jonah Kuhio Kalaniana'ole Pi'ikoi. Prince Kuhio reigned over the House of Kalakaua when the Kingdom of Hawai'i was overthrown in 1893. He later went on to become a politician in the Territory of Hawaii as delegate to the United States Congress. He is the first native Hawaiian and only person ever elected to that body who was born a royal. And, his birthday is a Hawaii state holiday.
