What is formally (not de facto) the capital of Taiwan?

Officially, the Republic of China (ROC) maintains its claim to be the legitimate government of the Chinese mainland, with a capital at Nanjing.

Thus, formally, Taipei is only the capital of Taiwan province of the ROC, and administered as a separate municipality. De facto, Taipei functions as the capital of the ROC on Taiwan.

Tainan was established as the capital of Taiwan in 1661 and remained capital until 1887 during the Qing Dynasty.

The government on Taiwan recognizes the mainland city of Nanjing (spelled Nanking in Taiwan) as its official capital, and designates Taiwan’s largest city of Taipei as its temporary capital.

The Republic of China claims Nanjing as its 'de jure' capital.
