Chiang Kai-shek helped unify China and then led the country from 1928 until he was defeated by Mao Tse-tung and the Communist forces in 1949. He then moved the Republic of China to Taiwan, where he ruled until his death in 1975. This 76-meter-tall (249-foot) monument consists of a white octagonal building with a blue tiled roof and is Taipei's most famous landmark. Opened in 1980, it sits in 25-hectare (61-acre) Memorial Park, surrounded by koi-filled ponds and gardens planted with plum and cherry trees. The Taiwanese government is currently considering repurposing the memorial to shift the focus on Chiang to the broader topic of the history of Taiwan.
