Pahukini (many drums) is a heiau located on the slopes of Kapa‘a and at one time overlooked the site of an ancient adze quarry. Below the heiau stretches the expanse of the Kawainui wetlands. Said to have been built by 14th century Tahitian Chief Olopana, it has also been listed as being named Moʻokini (many lineages) and also Makini (contraction of make kini (many deaths.))
The stacked rocks measure approximately 120 x 180 feet with an adjoining 32 x 38 foot structure on the north wall. Several interior terraces are found where the grass houses, oracle tower and perhaps wooden carvings stood. Pahukini heiau commands a sweeping view of low hills, the spreading expanse of the abandoned Kawainui fish pond once used by the ancient Hawaiians, and the present city of Kailua where a major Hawaiian settlement was on the shores of Kailua Bay.
