The Longevity Hill was originally called the Wengshan Hill. It was renamed by Emperor Qianlong in 1752, during the Qing Dynasty (1644-1911), when he constructed the garden. The hill is about 60 meters (196.9 feet) high and houses many buildings positioned in sequence. The front hill is rich in splendid halls and pavilions; while the back hill, in sharp contrast, is quiet with natural beauty.

At the foot of the front hill, an ancient-style archway provides the main entrance for climbing the hill. On the way up, visitors may see the major structures neatly ordered along a north-south ascending axis: Gate of Dispelling Clouds (Paiyunmen), Second Palace Gate (Ergongmen), Hall of Dispelling Clouds (Paiyundian), Hall of Moral Glory (Dehuidian), Tower of Buddhist Incense  (Foxiangge) and the Hall of the Sea of Wisdom on top of the hill. The most noteworthy structure of the back of the Longevity Hill is a building complex in Tibetan lamasery style. It is considered to be a miniature Potala Palace, the most famous resort of Lhasa in Tibet.
