This is the final study from a three-year research project. The two previous studies were on the structural relics left behind by the Bunun and the Japanese, including buildings left at old Bunun settlements, road networks, and other transportation facilities, the old sites of police outposts and auxiliary facilities, and memorial objects. Using the data collected from the previous two years as its base, and combining architectural studies, regional studies, and ethnology, the purpose of the study is to preserve these structures in their original location or create a comprehensive plan to restore them. The study also evaluated the feasibility of relocating the structures in questions, as preparation for further research projects.
