Lanyu
Orchid Island( Lanyu) Weather Station is situated at the topmost point of the Island and is regarded as one of the best spots for excellent views. First built in 1940 by the Japanese government for strategic purposes during World War II,the station now overlooks Badai Bay at west,Ivalino Tribe and Dongqing Bay at the east,and poetic mountain views at the south. Visitors can still find bullet holes on its walls.
