September 2 is the birthday of Hawai’i’s last reigning monarch, Lili’uokalani. Born in a grass house in 1838 and adopted by Hawai’i’s ruling dynasty, the infant girl who would become Hawai’i’s last queen began her tumultuous life 174 years ago at the base of an dormant volcano in Honolulu.

For the past several years, historians, Hawaiian cultural practitioners, and others who keep Lili’uokalaini’s memory alive, have gathered at the grounds of ‘Iolani Palace on her birthday to lead walking historical walking tours in an event called Mai Poina (Don’t Forget.) The tour on her birthday sold out but there are still a few spots left this coming weekend, September 7-9.
