Luakini From Wikipedia,

In ancient Hawai'i, a luakini temple, or luakini heiau, was a Native Hawaiian sacred place where human and animal blood sacrifices were offered.

In Hawaiian mythology, luakini heiaus were first established by Pa'ao, a legendary priest credited with establishing many of the rites and symbols typical of the stratified high chieftainships of the immediate pre-European-contact period. Modern archaeologists no longer believe in a historic Pa'ao, but many Native Hawaiians still believe that he was a historical figure, and often vilify him for introducing what they now see as the bloody, barbarous rites of the luakini heiau.
