Nunuk Ragang is a site traditionally considered as the location of the original home of the ancestors of the Kadazan-Dusun natives who inhabit most of northern Borneo. The site, nearby a village named Tampias, is located at the intersection of the left (Liwagu Kogibangan) and right (Liwagu Kowananan) branches of the Liwagu River to the east of Ranau and Tambunan in Sabah. The two river branches joined up to flow into the Labuk river and drain out into the Sulu Sea. At the site, and under a giant banyan tree, a settlement referred to as Nunuk Ragang was founded. The giant banyan tree was said to be able to give shade to a longhouse sheltering 10 families in it. The legend about Nunuk Ragang had been passed down via oral traditions to the younger generations. No archaeological dig has been carried out to establish the veracity of the legend. Under the strong influence of the modernisation, with the accompanying strong emphasis on other bigger encompassing cultures, and coupled with the passing of older generation, interest in this heritage will wane and disappear.
