The Haunting of Ulupō Heiau: Spirits of the Ancient Temple and the Human Sacrifices

What really happened in the ancient temple in Oahu in Hawaii known as Ulupō Heiau. According to stories, this might have been a place of human sacrifices and it is said that spirits of the many who died in rituals are now roaming the place for eternity.

On the lush slopes overlooking the Kawainui Marsh in Kailua, Oʻahu, the Ulupō Heiau State Historic Site is one of Hawaii’s oldest and most sacred sites. Dating back to the 16th century, this massive stone platform, with its carefully stacked rock walls, was once a significant temple—an altar where offerings were made to the gods, where chiefs sought guidance, and where warriors prepared for battle.

The big pile of rocks has signs telling visitors: “Sacred grounds, please do not remove stones”. Yet, for all its cultural and historical significance, the heiau is also known for something far more unsettling: its haunted reputation.

What really happened in the ancient temple in Oahu in Hawaii known as Ulupō Heiau. According to stories, this might have been a place of human sacrifices and it is said that spirits of the many who died in rituals are now roaming the place for eternity. — **Ulupō Heiau State Historical Site:** Kailua, Hawaii, on State and National Register of Historic *Places*.

Ulupō Heiau and its Sacred History

Ulupō Heiau, which means “night inspiration,” was believed to have been constructed by the menehune, Hawaii’s mythical race of small, industrious people who built many of the islands’ ancient structures. It is by all accounts very old, perhaps even more than a thousand years old. However, the heiau’s true purpose and use evolved over time.

Originally a marpele heiau ho‘oūlu ‘ai, a farming temple to ʻāina, where rituals were conducted to ensure bountiful crops, Ulupō eventually became a heiau pōhaku, a stone-walled heiau dedicated to Kāne, the Hawaiian god of creation, sunlight, and freshwater. Or perhaps even a Heiau Luakini dedicated to success in war and was perhaps even the sight for human sacrifice. The site, with its imposing rock walls—some over 30 feet high—became a focal point for the aliʻi (chiefs) of Oʻahu and an important center for spiritual and political life.

As time passed and Hawaii underwent sweeping changes, including the introduction of Christianity and Western influence, Ulupō Heiau fell into disuse.

Human Sacrifices

As mentioned the stones are said to have been used for human sacrifices as well and has become a part of its haunted legend. According to some it was during war times when King Kamehameha came to this place with his warriors and priest to give thanks to his new god, the war god. It was said he needed more blood and Kamehameha said he needed five people every day as a sacrifice from the islands. But the village chief was an overachiever and killed five people every day just in this one place, just to be sure of the rituals success.

How many of these sacrifices happened, if there were any at all? None? perhaps as much as 80 000 people as some ghost tours proclaim? It’s definetly not certain at all, but ghost stories and creepy legends have been created because of the stories.

Ghostly Legends and Hauntings

According to some stories there are tens of thousands of bones buried within the walls of this particular Heiau, and some believe that the spirits of those lingers. The air around Ulupō Heiau seems thick with unseen energy, and those who come here often report a strong feeling of unease, as if they are being watched by unseen eyes.

Locals and visitors alike have spoken of ghostly apparitions roaming the grounds, particularly around dusk or just before dawn. Figures dressed in ancient Hawaiian garb have been seen moving silently through the shadows. Some witnesses describe seeing inexplicable lights—glowing orbs or flickering lantern-like flames that dance among the stones and trees. These lights, which appear and disappear without warning, are often attributed to the wandering spirits of ancient kānaka maoli (native Hawaiians).

Many have also reported hearing the faint sounds of chanting—deep, resonant voices carrying on the wind, speaking in the old Hawaiian language. These chants, believed to be ancient prayers or battle cries, add to the eerie atmosphere of the heiau, as if the spirits of those who once gathered here are still engaged in their sacred rituals.

The Presence of the Night Marchers

One of the most chilling legends associated with Ulupō Heiau involves the night marchers, or huaka‘i pō—ghostly processions of ancient Hawaiian warriors who are said to traverse sacred sites on specific nights, often under the cover of darkness. According to Hawaiian lore, the night marchers are the spirits of fallen warriors or chiefs who roam the islands, retracing the paths they walked in life. They are known to march in formation, accompanied by the sound of pahu drums and the blowing of conch shells.

At Ulupō Heiau, it is said that the night marchers pass through on moonless nights. Those who have encountered them describe feeling an overwhelming sense of dread and are compelled to drop to the ground and avert their eyes to avoid drawing the spirits’ wrath. Those who fail to show proper respect are said to be struck down by an invisible force or become possessed by a spirit, leaving them lost or disoriented for days.

An Unsettling Presence

Visitors to Ulupō Heiau often speak of an “unseen presence” that follows them as they walk through the area. Some claim to feel a sudden chill or hear footsteps behind them, only to turn around and find no one there. Others feel an inexplicable pressure or heaviness, as if something unseen is pressing down on them. These experiences, coupled with the whispered chants and ghostly apparitions, make Ulupō Heiau a place that can feel profoundly unsettling, even to the bravest souls.

For those who venture to Ulupō Heiau, it is a place where history is still alive—a place where the spirits of ancient Hawaiians continue to guard their sacred ground. Whether you come to pay your respects, seek a glimpse of the supernatural, or simply explore the island’s history, remember that this is a site of profound cultural and spiritual importance. Tread carefully, for the spirits of Ulupō Heiau are said to be ever watchful, ensuring that their sacred temple is never forgotten.
