About
Keaʻiwa Heiau is an ancient 16th-century Native Hawaiian sacred site (heiau hoʻōla) situated at the summit of ʻAiea Heights on Oʻahu. Constructed under the direction of High Chief Kākuhihewa and his high priest Kahuna Keaīwa, the open-air dry-stacked basalt structure served as Oʻahu's premier training sanctuary for traditional herbal healers (kahuna lapaʻau).
The stone enclosure functioned as both a place of spiritual prayer and a practical medical academy. Student practitioners underwent decades of study here, learning diagnostic methods, spiritual chanting, and the preparation of herbal remedies (lāʻau lapaʻau) cultivated in surrounding botanical gardens.
Today, Keaʻiwa Heiau is protected within the 384-acre Keaīwa Heiau State Recreation Area. Rededicated in 1951, it remains a active place of pilgrimage and cultural stewardship, standing as Oʻahu's most intact surviving monument to traditional Native Hawaiian medicine.

Preserving Lāʻau Lapaʻau in Secret
1819
When King Kamehameha II abolished the kapu system in 1819, public temple rituals were discontinued across the islands. Local healers in the ʻAiea ahupuaʻa quietly protected their ancestral botanical knowledge within family lineages. Their quiet devotion ensured that Hawaiian medical knowledge survived into the modern era.
