The remaining platform of the 'Ale'ale'a heiau is 127 feet long, 60 feet wide and an average of 8 feet high. 'Ale'ale'a was once the primary temple (heiau) for the pu'uhonua before the building of Hale o Keawe. While it served as the main heiau for the area, 'Ale'ale'a probably had thatched huts and several carved images (ki'i) around it. It was constructed in seven stages. One of the early stages had been dated, and it was discovered that 'Ale'ale'a is the oldest heiau site in the area.
