Located at the northwest corner of Shichahai, Prince Kung's Mansion is a typical royal garden. The residence has a central axis and also adopts a symmetrical approach. Built at the end of the 18th century, it is the best preserved royal residence of the Qing Dynasty in Beijing, and is called the "Pearl of Shichahai".

In the late Qianlong period, it was the residence of Heshen, the grand secretary. It was later granted as the royal residence of Prince Kung Yixin. There is a unique garden named Zuijin Garden behind the mansion, which covers an area of about 30,000 square meters.

The garden is surrounded by horseshoe-shaped hills on the east, south and west sides and the scenery in the garden is chic and exquisite. It is a national key cultural relics protection unit. The front part of the mansion was formerly the workplace of the Dream of the Red Chamber Institute of the China Academy of Art. After the unit was moved out, it has been restored and is now open to visitors. A part of the Prince Kung's Mansion is now open to visitors as the former residence of Guo Moruo.
