The Chongzheng Hall, also called as the Main Hall, is located at the midmost of the front yard on the central axis. It was built during the Tiancong reign (1627-1636) in the Late Jin Dynasty (1115-1234). In the first year (1636) of the Chongde reign, it was renamed as the Chongzheng Hall, and is also widely known as the Gold Bell Hall. The hall has the front and rear porches and is surrounded by the stone railing carved with kylins, lions, sunflowers, lotuses and so on. The pillars supporting the porch are square. There are hornless dragons puffing water under the roof pillars. The roof is covered with yellow glazed tiles with a green edge. The pillars in the hall are round and two of them are connected with a carved dragon. The dragon’s head is stretching out of the eaves, while the tail is attacking straight into the hall. Hence the practicality and decoration are combined together, not only adding the imperial spirit to the hall, but also making the architecture appearance pleasing to the eye.
The ceiling has no decorations, and only patterns of blue lands and white clouds are painted on the roof boarding, making the hall look lofty and elegant. On the beams, purlins, rafters and square wood, there are colored paintings depicting dragons in the clouds, immortal peaches and others. In the center of the hall, a flight of steps was built in the shape of the Chinese character 凸 (convex). In front of the flight, there is a tortuous golden dragon in lifelike posture on a pillar. The folding screen, throne as well as the sundial, measuring tool and other articles on display were all set up during the Qianlong reign. This hall was used by Abahai to handle daily military and political affairs and meet foreign envoys and representatives of the minorities on the frontier. In the 10th year (1636) of the Tiancong reign, the ceremony of changing the title of the Late Jin to the Daqing was also held here. After the Qing Army entered the Shanhai Pass, the capital of the Qing Dynasty was moved to Beijing. Since then the emperors of all dynasties used it as a temporary court when they inspected the east area.
The Dazheng Hall, initially called as the Grand Hall, the Eight-Square Hall or the Big Yamun, was named as the Dugong Hall in the first year (1636) of the Chongde reign and was changed to the current name upon the order of Emperor Kangxi. In front of the hall, there is a space 195 meters long from the south to the north and 80 meters wide from the east to the west. Two ways were paved from the midmost. There are ten square pavilions arranged on the east and west, known as the Shiwang Pavilion (the Pavilion for Ten Kings). These were the places where the two kings and eight ministers handled governmental affairs. It is a unique characteristic of the layout for the Shenyang Imperial Palace. Behind the Shiwang Pavilion is the Dazheng Hall, which was structured with eight-square eaves and posts, connected by rabbets and rivets. The eight sides of the hall are wooden doors with grids without any bricks and stones, which can be opened at will. Under the Hall, it has Buddhist seat foundation and surrounded by bluestone rails with a variety of fine carving. The inside of the hall is bright with the sunshine penetrating from the top. The pendentive, sunk panel, ceiling and others are all extremely exquisite and unique. The roof of the hall, like the Chongzheng Hall, is covered by yellow glazed tiles edged with a green border. There are 16 ridges made of full color glazed tiles on the roof. In front of the main gate, there are two tortuous golden dragons carved on a pillar.
The Wensu Pavilion is the principal architecture on the west axis of the Shenyang Imperial Palace. In front of the pavilion, there is the stage and the Yangxi Room. Behind the pavilion is the Yangxi Room, which was first built in the 47th year (1782) of the Qianlong reign, specially used for treasuring up Si Ku Quan Shu (the Complete Library in the Four Branches of Literature) and also the place where the emperors read and enjoyed playgoing when they visited Shengjing on their eastern tours. The style of the architecture follows the Tianyi Pavilion in Ningbo City, Zhejiang Province. The Yangxi Room has front and rear porches, and its roof is covered with black glazed tiles edged with a green border. The front and rear eaves and pillars are decorated with green lichen.
