Tonga, Tonga Gate
The megalithic structure of Haamong-a-Maui (“the burden of the god of Maui”), also known as the “Gate of Tonga”, is located in the north of the island of Tongatapu.
It consists of three limestone coral slabs, the length of each of which is about 6 meters, and the weight of each vertical is not less than 20 tons. Date of construction of buildings, as well as its purpose is unknown. According to oral tradition, it is supposedly appeared at the beginning of the 13th century.
There is a version that Haamong-a-Maui could serve as an entrance to the royal territory of the ancient capital Tonga that existed here in the past.
