Hall of Harmony and Peace is the main palace of Yonghe Lamasery and inside three bronze Buddhas are displayed - Sakyamuni in the middle, Kasyapa-matanga on the right and Maitreya on the left. There are 18 Arhats (statues of Buddha disciples) positioned on both sides of the Hall. The picture on the west wall is of Avalokitesvara with its thousands of hands and eyes.

North of the Hall of Harmony and Peace is Yongyoudian (Hall of Everlasting Protection), which was Emperor Yongzheng's living room when he lived there as a young prince and, at the time of his death his coffin was placed there. Now, a statue of Bhaisajya-guru is located there and sacrificial offerings are made to it.
