Ulupo Heiau State Historic Site, Ancient temple site in Kailua, Hawaii
Ulupō Heiau is an ancient Hawaiian temple site in Kailua, featuring a stone platform approximately 140 by 180 feet with walls rising to about 30 feet, built using traditional Hawaiian construction methods. The structure showcases how skilled workers layered stones without mortar to create a durable platform that has lasted centuries.
The site reached its peak importance around 1750 as a center of spiritual and political power in the region. After Maui chief Kahekili conquered Oahu in the 1780s, the temple fell out of use and was eventually abandoned as the new ruling powers shifted focus elsewhere.
The site served as a place of spiritual devotion, first honoring agriculture and later transformed into a space for warrior rituals under Chief Kuali'i in the late 1700s. This shift reflects how the community's connection to the location evolved with changing leadership and needs.
The site is accessible through an adjacent YMCA facility, making it easy to reach the ancient platform and explore the grounds. Visitors should wear comfortable shoes and bring water, as the location has limited shade and can get quite hot during the day.
The massive stones used in construction were brought from Kualoa, a location over 15 kilometers away, revealing the remarkable engineering abilities of ancient Hawaiian workers. This enormous effort required careful planning and significant manpower to quarry, transport, and place each stone precisely.
