    Situated in the heart of Beijing, the Forbidden City－now called the Palace Museum－covers an area of 1,120,000 square meters. During nearly six hundred years, the palace served as the residence and court of twenty-four emperors. It consists of various structures built in accordance with the traditional Chinese architectural hierarchy（层次、结构）and designed to reflect imperial power and authority.

Entering from the south, visitors will see a succession of halls and palaces spreading out on either side of the central axis. The magnificent architectural complex and the vast holdings of paintings, calligraphy, ceramics, and antiquities of the imperial collections make it one of the most prestigious museums in China and the world. In 1987 it was listed as a UNESCO World Heritage site.

The Palace Museum can be approached through the Gate of Heavenly Peace. Immediately to the north of the Palace Museum is Prospect Hill, while on the east and west are the Wangfujing and Zhongnanhai neighborhoods. Visitors will be excited to find various historic sites, scenic parks, shopping malls, museums, and theatres in the vicinity of the Forbidden City. Conveniently located bus stops and subway stations provide easy access to transportation.
