Inside Battery Randolph

Inside, displays cover Hawaiʻi’s history from early Hawaiian military systems to modern conflicts. The story begins long before the arrival of Europeans and continues through the era of King Kamehameha, World War II and the Vietnam War.
Artifacts, vehicles and the rooftop gunship
