The story
Around 1200 CE, the Tu'i Tonga, Tonga's sacred kings, ruled a large ocean empire. The 11th Tu'i Tonga, Tu'itatui, built Ha'amonga 'a Maui, which means the Burden of Maui.
The gateway is made of three blocks of coral limestone. Each upright is about 5 meters tall, and the top beam rests in notches cut into them. Each stone weighs around 30 to 40 tonnes.
Its name comes from a legend that the demigod Maui carried the stones here on a pole over his shoulder. In 1967, King Taufa'ahau Tupou IV suggested that a carving on the top beam marks the direction of sunrise on the solstices, so it may have worked like a calendar.
How it ended
Over time, the royal center of the Tu'i Tonga moved to Lapaha, and the gateway was no longer the center of power. But it still stands where it was built, after more than 800 years.
What life was like
Tonga's people farmed yams and taro, fished and sailed great double-hulled canoes between islands. The Tu'i Tonga were believed to come from the sky god and had huge power. Builders moved giant stones without metal tools, probably by rafts, rollers and many workers.
Wow facts
- Each stone weighs around 30 to 40 tonnes.

How we know
Tongan oral history names the king who built it. Visitors described it from the 1700s on. Modern studies measured the stones and checked how the carvings line up with the sun.
What you would see today
Visitors walk up to the trilithon in a small park on Tongatapu. Each year on the solstices, people gather to watch the sunrise. It is a national symbol of Tonga.
