This is the largest and most famous of the heiau (ancient Hawaiian places of worship) on Moloka'i. It is an enormous stone platform measuring 120 feet wide by 320 feet long. In ancient times, priests conducted human sacrifice at the heiau, and villagers avoided and feared it; with good reason. According to legend, it was built during the time of the Menehune, who proceeded to baptize it with the blood of local sons. The heiau can be visited on foot or on horseback. As with all such sites, visitors are expected to show respect and stay within marked boundaries.
