Built in 1771, the Putuo Zongcheng Temple is a most resplendent and sweeping one. It covers an area of 220,000 square meters, and is similar to the Potala Palace in Lhasa. This temple was built for celebrating the emperor Qianlong's birthday. Zang-style architectures are displayed thoroughly there. A square architecture named Big Red Platform is the principal part, on which there are three halls. The tops of the halls are covered with the copper gold tiles, thus a very precious monument. This temple was used to hold important religion ceremonies and for the emperors to interview the heads of the Minorities and some ministers in the past.
