The palace grounds are divided into two parts: the Front Palace (Qianchao) to the south and the Inner Palace (Neiting) to the north. The Front Palace consists chiefly of three halls -- the Hall of Supreme Harmony (Taihedian), the Hall of Central Harmony (Zhonghedian) and the Hall of Preserving Harmony (Baohedian). Here, important ceremonies, such as the accession of a new emperor to the throne and the emperor's birthday and wedding, were held.
The Inner Palace mainly includes the Palace of Heavenly Purity (Qianqinggong), the Hall of Prosperity (Jiaotaidian) and the Palace of Earthly Tranquility (Kunninggong), where emperors and empresses lived. Behind them is the Imperial Garden.
On each side of the inner three great halls are six eastern palaces and six western palaces, respectively, which were used as residences for concubines.
The Palace Museum in the Forbidden City has the country's largest collection of ancient art works, some of which are invaluable national treasures. Art works in the museum's collection total 1,052,653, including paintings, pottery, bronze wares, inscribed wares, toys, clocks and court documents, etc.
In 1987, the Forbidden City was included in the World Heritage List of UNESCO.
