About

Ulupō Heiau is one of Oʻahu's largest and most sacred open-platform stone temples, situated at the edge of the expansive Kawainui Marsh in Kailua. Constructed from tens of thousands of basalt fieldstones, the site originally served as an agricultural temple (heiau mapele) consecrated to the deities Lono and Kāne.

Rising 30 feet above the surrounding wetlands, the massive stone terrace channels natural freshwater springs into historical loʻi kalo (taro patches). Today, Ulupō Heiau remains an active indigenous sacred site (wahi pana) restored and maintained by community cultural stewards.

History by Decade

700s–1100s

Early Polynesian settlers on Windward Oʻahu establish an agricultural temple atop a natural spring overlooking Kawainui lagoon. The site is dedicated to Lono and Kāne to ensure water flow and crop fertility.

1200s–1500s

As agricultural systems expand, High Chief Kākuhihewa establishes his royal court in Kailua. Ulupō Heiau becomes the principal ceremonial complex for managing the rich agricultural yield of the region.

1600s–1700s

High Chief Kualiʻi enlarges the stone platform using basalt rocks transported from distant island districts. During later 18th-century warfare, invading chiefs adapt the heiau for statecraft and military rituals.

1800s

Following the 1819 abolition of the Kapu system, formal temple activities cease and wooden structures decompose. The surrounding land transitions to agricultural leases worked by Hawaiian, Chinese, and Japanese farmers.

1900s–1980s

Archaeologist J. Gilbert McAllister surveys Ulupō in 1933. The Territory of Hawaiʻi acquires the land in 1954 to prevent suburban development, leading to its 1972 placement on the National Register of Historic Places.

1990s–Present

Community cultural organizations partner with State Parks to restore the surrounding loʻi kalo. Today, Ulupō serves as an active sacred site, outdoor classroom, and focal point for community land stewardship (mālama ʻāina).

Architecture & Facilities

Ulupō Heiau is an open dry-stone platform temple (heiau poʻokanaka) built using traditional Hawaiian masonry techniques without mortar. Designed as an elevated unroofed stage built into the hillside above spring-fed wetlands, its massive stone terraces integrate seamlessly with the natural hydrological landscape.

Building Materials

Volcanic Basalt Fieldstones (Pōhaku)

Unmortared local basalt rocks formed the structural core and interior platform terraces.

Transported Facing Cobbles

Smooth exterior stones hand-transported via long human chains from distant valleys like Kualoa.

Interior Rubble Fill (ʻAlā)

Smaller basalt river stones used as dense interlocking fill inside the massive retaining walls.

Natural Spring Channels

Basalt water pathways engineered at the base to direct freshwater flow into farming fields.

Interior Features

Upper Stone Platform Terrace

A large flat open stone surface measuring 140 by 180 feet used for ancient ceremonial rites.

Spring-Fed Basin Base

The lower western edge where freshwater emerges directly from beneath the stone foundation.

Outer Retaining Wall Face

A 30-foot battered stone wall engineered to resist seismic shifts and soil movement.

Sacred Ceremonial Precinct

The elevated central platform area historically housing wooden altars and carved kiʻi.

Temple Grounds

Surrounded by active loʻi kalo (taro patches), native flora, freshwater spring channels, and bordering the 830-acre Kawainui Marsh wetland sanctuary.

Additional Facilities

Public park entrance area with informational signage and access pathways along the perimeter of the taro fields.

Religious Significance

In indigenous Hawaiian spirituality (Ao Hawaiʻi), sacred sites (wahi pana) are living conduits of spiritual power (mana). Ulupō Heiau was consecrated to bridge human agricultural effort with the divine forces governing water, weather, and life.

To consecrate fresh water springs, ensure agricultural fertility, and express community gratitude to the divine forces of nature.

Sacred Ordinances

Chants and Protocols (Oli & Hoʻokupu)

Traditional chants and sacred protocol offerings performed to honor ancestral spirits and ask permission before entering.

Agricultural Consecration

Ceremonial rituals dedicated to Lono to invoke rain, crop abundance, and peaceful governance across the ahupuaʻa.

Land Stewardship Protocol (Mālama ʻĀina)

Active physical care and cultivation of the land viewed as a sacred spiritual duty linking humans to ancestors.

Honoring Lono and Kāne

Ulupō's dual association with Lono (god of rain and fertility) and Kāne (god of fresh water) emphasizes the divine balance necessary for life. The bubbling springs directly underneath the platform stand as a perpetual manifestation of Kāne's life-giving energy.
