Omo Sebua

The omo sebua is the traditional chief's residence of the Nias people, found on Nias island roughly 140 kilometers off the western coast of Sumatra in Indonesia's North Sumatra province, and its scale and craftsmanship reflected the wealth and status of Niassan aristocracy. Its sole access is a narrow staircase with a small trap door above, making the house nearly impregnable during the frequent inter-village conflicts the island once saw, and its steeply pitched roof rises to about fifty feet with dramatic gables at front and rear, giving it a distinctive towering silhouette. The structure rests on massive ironwood piles set on stone slabs with diagonal bracing beams, an arrangement that gives it real earthquake resistance, and its wooden elements are slotted together rather than nailed or bound. Inside, hardwood surfaces carry intricate bas relief carvings of ancestors, jewelry, animals and boats, reflecting Niassan ideas about cosmic balance expressed through paired male and female artistic elements.
