At the foot of Tiantai Mountain, Guoqing Temple was built in 598 in the Sui Dynasty (581-618 AD) according to the last wish of 'Wisdom', an eminent monk. It is said that he founded the Chinese Tiantai Sect of Buddhism. Later its doctrines were spread abroad, mainly to Korea and Japan. Guoqing Temple has been restored many times in later dynasties. The most recent renovation was during the Qing Dynasty (1644-1911). Guoqing Temple now is a grand and unique architectural complex consisting of more than 600 rooms and 14 halls. It is one of the best preserved large temples in China.
