Thousands of years ago, there was a huge volcanic activity in Seonginbong and after that, the underneath part subsided and the Nari basin was formed.
The Seonginbong is now an inactive volcano and these days, people live in the basin and grow crops.
But in the Joseon dynasty, King Taejong announced a policy to the people who had lived there to empty the Ulleungdo.
The Tumakjip houses in Nari are built with Ulleungdo hemlock[3] (Tsuga diversifolia) and Engler’s beech[4] (Fagus engleriana), shaping them in a hash sign with soil attached in between.
