Located on the island of Tongatapu in Tonga, Ha’amonga is a stone trilithon that stands over five meters high and almost six meters long.
This trilithon consists of three slabs of coral limestone and each slab weighs anywhere from 20-40 tons. Two stand vertically while the third sits atop them both. It was built under the rule of Tu’i Tonga Tu’itatui, as a sort of gateway that led to his royal throne. It’s also said to symbolize brotherhood. In some myths it’s believed that since the stones are much too heavy for a mortal to handle, Maui, the god, built it.
