A vast majority of tourists who visit Beijing for the first time consider the Forbidden City as a place they must see. The Forbidden City, known as Gugong in Mandarin, once served as the imperial palace for 24 emperors during the Ming and Qing dynasties. It is a symbol of ancient China. Although it is no longer China's political centre, you can still feel its former glory once you are within the courtyard and surrounded by the high walls. Its long history has left behind a large amount of precious architecture and cultural relics, making it one of the most important cultural heritage in modern China.
