Lore & Background
According to Sumbanese oral tradition, Flores and Sumba were once connected by the Kataka Lindiwatu, an ancient stone bridge. The island was part of the Majapahit empire, and the name 'Sumba' first appeared in Javanese manuscripts from that period. Sandalwood was the main export, leading to the island being called Sandalwood Island.
Reader's Guide
Sumba holds significance as one of the last places on Earth where societies still build megalithic monuments for collective burials, with about 100 new megalithic tombs constructed annually. The island's cultural systems vary: western Sumba has segmentary societies, while northern and eastern Sumba have stratified caste-based societies. Ecologically, Sumba is part of the Wallacea region, with a mix of Asian and Australasian flora and fauna. It hosts seven endemic bird species, including the threatened Sumba hornbill. The island's landscape features limestone hills rather than volcanoes, with a dry season from May to November. Recent research suggests Sumba may have detached from the Southeast Asia margin rather than being part of Gondwana.

Frequently Asked Questions
What are Sumba's living megalithic traditions?
Sumba is one of the few places on Earth where megalithic burial customs—massive stone tombs and ritual practices—have been maintained continuously for thousands of years without interruption. These traditions are still actively practised by local communities rather than existing only as archaeological ruins.
Why did European colonial powers target Sumba?
The island's dense forests yielded high-quality sandalwood, making it a prized source of that fragrant timber during the colonial era. Sandalwood became Sumba's defining historical export, drawing trade routes and foreign interest to the region.
What is the largest settlement on Sumba?
Waingapu serves as the island's biggest town and its primary urban centre. It functions as the main hub for commerce, administration, and transport across the island.
What makes Sumba's biodiversity distinctive?
The island falls within the Sumba deciduous forests ecoregion, a habitat type found on very few landmasses worldwide. Seven bird species are found nowhere else on the planet, all restricted to Sumba's forests and grasslands.
