Haʻamonga ʻa Maui
A Tongan king's stone gateway, the 'Stonehenge of the Pacific'

In the 13th century Tuʻitātui, the eleventh Tuʻi Tonga, raised a trilithon of coral limestone slabs, each weighing tens of tonnes, in the east of Tongatapu. The name means 'the Burden of Maui': legend says only the demigod could have carried such stones. It is known as the 'Stonehenge of the Pacific'.
