About
Pu'u o Mahuka Heiau State Historic Site is the largest ancient Hawaiian temple (heiau) on O'ahu, covering nearly two acres on Pupukea Ridge 300 feet above Waimea Bay. Constructed without mortar using hand-stacked basalt rocks, this massive open-air sanctuary served as a heiau luakini dedicated to Kū, the deity of statecraft, victory, and societal order.
For over seven centuries, the surrounding Waimea Valley was known as Ahupua'a o Nā Kahuna ("Valley of the Priests"), functioning as the hereditary spiritual center of the Pā'ao priesthood line. High priests and ruling chiefs conducted solemn rituals here to maintain sacred balance (lōkahi) and validate sovereign rule until the traditional kapu system was formally abolished in 1819.
Today, the site is preserved as a National Historic Landmark and a sacred site (wahi pana). Active Native Hawaiian cultural practitioners continue to honor the sanctuary, which offers panoramic vistas across Waimea Bay and historic line-of-sight views toward Kaua'i.
