Mokuula is a tiny island now buried beneath an abandoned baseball field in Maluulu o Lele Park, Lahaina, Hawaii. It was the private residence of King Kamehameha III from 1837 to 1845 and the burial site of several Hawaiian royals. The island was and continues to be considered sacred to many Hawaiians as a piko, or symbolic center of energy and power. According to Klieger, "the moated palace of Mokuula...was a place of the "Sacred Red Mists," an oasis of rest and calm during the raucous, rollicking days of Pacific whaling." When the capital of Hawaii moved from Lahaina to Honolulu, Mokuula fell into disrepair. By 1919, the county turned the land into a park. Efforts are currently underway to revive the site.
It was added to the Hawaii State Register of Historic Places on August 29, 1994, and to the National Register of Historic Places on May 9, 1997 as King Kamehameha III's Royal Residential Complex.
