By the end and in the wake of World War II the Dadu Plateau had over a dozen bunkers and artillery positions to protect Shuinan Airport and Qingquangang Airport. Although these bunkers no longer have much military significance, they still have historical and cultural value, and they are special landmarks on the Dadu Plateau. Therefore the Taichung City Government designated these 12 bunkers in 2006 as ‘historic buildings’ to give them official monument status as well as protection and preservation.
The park currently has two cylindrical anti-air-raid bunkers (no. 3 and 4) and four machine-gun bunkers as well as one bell-shaped bunker at the northern edge of the park (no.5), offering visitors a peek into the history of bunkers on Dadu Mountain.
