Behind the Hall of Earthly Tranquility
is the Imperial Garden where the imperial family members recreated themselves. It was built up in 1420 and remains unchanged in its original layout. The garden with an area of about 1.2 hectares (2.97 acres) has more than twenty structures distributed symmetrically but not prudishly.
The garden centers Qin'an Dian (Hall of Imperial Peace), with other buildings framed by a background of old trees. Surrounding the Hall of Imperial Peace, four dainty pavilions are of a great originality in their styles and are named after four seasons of a year. The steep rockery with a chic pavilion on in the north was where the emperor and empress climbed up to view the distance on the lunar September 9th. Even the paths convey a distinct flavor. They are paved with pebbles with different colors, forming a variety of designs portraying people, flowers, scenery or stories.
