Ulupo Heiau
Ulupo Heiau is an ancient site that served as a religious site where native Hawaiians likely came for bountiful harvests, and then success in war. The stone platform of Ulupo Heiau measures 140 feet x 180 feet, while the walls were as high as 30 feet. Although it probably began as an agricultural heiau with springs feeding crops of taro, banana, sweet potato, and sugarcane along the fringes of the 400-acre Kawai Nui pond, the great warrior chief Kualiʻi may have converted it to a heiau luakini where human and animal blood sacrifices were offered.
