Main image

The Badrulchau Stone Monoliths are a group of standing stone monuments on the island of Babeldaob in Ngarchelong state, Palau. The site is recognized as an archaeological landmark in the country.

Small clusters of upright stone pillars set in cleared areas comprise the visible remains at Badrulchau. Visitors encounter examples of megalithic stone construction rather than a single large structure.

The monuments date to Palau’s prehistoric period and are associated with the island’s traditional cultural landscape. They are part of the wider corpus of Micronesian megalithic sites studied for insights into pre-contact social organization.

The site sits on the northern part of Babeldaob island in Ngarchelong state, in the northern region of Palau. It is a coastal island location within Palau’s main island group.

  • Archaeological significance: Located on the northern coast of Babeldaob in Ngarchelong state, the site is one of Palau's most visible concentrations of standing stone monuments.

  • Respect local sensitivities: the stone monoliths are part of Palau's cultural landscape and may have spiritual significance to village elders.
  • Bring insect repellent and sun protection-moving between monoliths may require walking across open ground.
  • Hire a local guide from Ngarchelong to learn the oral histories attached to each stone; guides will keep visitors from touching fragile glyphs or features.
