Built during the reign of Emperor Qianlong, this group of buildings includes a main hall, an auxiliary pavilion and a stele inscribed with Emperor Qianlong’s essay on Longevity Hill and Kunming Lake. This is where the emperors and empresses stored their Buddhist scriptures and sculptures. It is also where they would go to recite scriptures and to pray. The auxiliary pavilion has two floors through which a four-storey, colored wooden tower stood. Inside this tower were scriptures and Buddhist statuettes. The tower could be turned to symbolize the cyclic chanting of scriptures.
