After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of Emperors of Successive Dynasties, was reopened to the public last weekend.
Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors.
It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School.
The temple’s Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the re-opening of the temple, jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use.
The renovation was done strictly according to that carried out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been re placed.
