One of the last remaining North Nias traditional villages, Siwahili Tumori has ten oval-shaped shaped houses over a century old.
Tumori is a traditional village located in the area of Gunungsitoli City, only 23 Km from Binaka airport with a travel time of 45 minutes.
The Tumori traditional village is one of the traditional villages in North Nias that is still awake which has 10 oval traditional houses and families that are more than 100 years old. Omo Hada Laraga, the term for traditional house oval shape in Nias language has its own characteristics and uniqueness because the whole part of the house (except the roof made of sago palm leaves) is made of wood and does not use iron pegs / nails to connect each link in the traditional house . In addition, the foundation pillars of houses which are also made of wood are not planted in the ground but are erected on rocks so that in the event of an earthquake this house will remain strong and not collapse. This was evident when an earthquake with a magnitude of 8.7 SR hit Nias in 2005.
The making of the Omo Hada Laraga building was once inspired by the ships used by the ancestors of Nias people who were known as accomplished sailors and also for their experiences during the tsunami and the massive earthquake that hit Nias in the 18th century, so they built houses on the hills with the form of clumps and ovals as a solution to the disaster. At first glance, the traditional houses of Nias do look like ships, especially on the sloping walls like a ship's body.
This traditional settlement was once an Öri (literally means ring, circle, and hereinafter referred to as a group of villages), a village group owned by the same clan of clans which is a territorial unit. This is evidenced by almost the entire population in this village and the surrounding villages surnamed Zebua. The village is Tumöri O'o, Orahili Tumöri, Tumöri Gada, Tumöri Balöhili, Sihare'ö Siwahili and Lölömoyo Tuhemberua. But the traditional villages that still survive today are only Tumori and Sihare'o Siwahili.
Sihare'o Siwahili is not far from Tumori, only a 5-minute drive. In this village there are also 5 Omo Hada fruits.
Traditional houses and the pattern of the South and North Nias villages have a significant difference, where the North traditional houses form a temporary oval in the shape of a rectangular. Likewise the village pattern, in the north the traditional house was built randomly and far apart while in the South fused to form the letter L or T with the king's house / nobility with the highest social status in the middle followed by other traditional houses whose order was adjusted to the status social in the village.
