Spend half a day exploring the headquarters of past emperors and the Nationalist government. The Palace includes the former offices of many top governmental officials, including Chiang Kai-shek and Sun Yat-sen, as well as the former residence of Sun Yat-sen. It is one the few places in mainland China where the flag of the Republic of China still flies. Informational placards around the palace are partly in English. Closed on Mondays.
