The Meteorological Observatory

It is located on one of Lanyu’s mountain tops at a height of 323.999 m. It had been constructed during the Japanese colonial era in order to observe the movements of typhoons in the Pacific Ocean. During the Second World War, it has been severely damaged by the US Army. Being renovated after the war, most sections are restored from the original Japanese model.
