King Wu was the first to declare Beijing the capital city in 1057 BC. Subsequently, the city has gone by the names of Ji, Zhongdu, Dadu, and finally Beijing when the Ming Dynasty Emperor ChengZu chose the name in 1421. Before 1949, Beijing was known as Peking by the Western world. After 1949, the city’s name returned to Beijing, as it is known today.
The Great Wall of China is a series of stone and earthen fortifications in northern China, built originally to protect the northern borders of the Chinese Empire against intrusions by various nomadic groups. Several walls have been built since the 5th century BC that are referred to collectively as the Great Wall, which has been rebuilt and maintained from the 5th century BC through the 16th century. Little of that wall remains; the majority of the existing wall was built during the Ming Dynasty.
The Forbidden City was the Chinese imperial palace from the Ming Dynasty to the end of the Qing Dynasty. It is located in the middle of Beijing, China, and now houses the Palace Museum. For almost five hundred years, it served as the home of emperors and their households, as well as the ceremonial and political center of Chinese government.
