Tian'anmen (the Gate of Heavenly Peace), is located in the center of Beijing. It was first built in 1417 and named Chengtianmen (the Gate of Heavenly Succession). At the end of the Ming Dynasty, it was seriously damaged by war. When it was rebuilt under the Qing in 1651, it was renamed Tian'anmen, and served as the main entrance to the Imperial City, the administrative and residential quarters for court officials and retainers. The southern sections of the Imperial City wall still stand on both sides of the Gate. The tower at the top of the gate is nine-room wide and five –room deep. According to the Book of Changes, the two numbers nine and five, when combined, symbolize the supreme status of a sovereign. During the Ming and Qing dynasties, Tian'anmen was the place where state ceremonies took place. The most important one of them was the issuing of imperial edicts, which followed these steps: (来源：http://www.EnglishCN.com)
1) The Minister of Rites would receive the edict in Taihedian (Hall of Supreme Harmony), where the Emperor was holding his court. The minister would then carry the decree on a yunpan (tray of cloud), and withdraw from the hall via Taihemen (Gate of supreme Harmony)
2) The Minister would put the tray in a miniature longting (dragon pavilion). Beneath a yellow umbrella and carry it via Wumen (Meridian Gate), to Tian'anmen Gate tower. 3) A courtier would be invested to proclaim the edict. The civil and military officials lining both sides of the gateway beneath the tower would prostrate themselves in the direction of the emperor in waiting for the decree to the proclaimed.
3) The courtier would then put the edict in a phoenix-shaped wooden box and lower it from the tower by means of a silk cord. The document would finally be carried in a similar tray of cloud under a yellow umbrella to the Ministry of Rites.
4) The edict, copied on yellow paper, would be made known to the whole country. Such a process was historically recorded as " Imperial Edict Issued by Golden Phoenix". During the Ming and Qing dynasties Tian'anmen was the most important passage. It was this gate that the Emperor and his retinue would go through on their way to the altars for ritual and religious activities.
On the Westside of Tian'anmen stands ZhongshanPark (Dr. Sun Yat-sen's Park), and on the east side, the Working People's Cultural Palace. The Park was formerly called Shejitan (Altar of Land and Grain), built in 1420 for offering sacrificial items to the God of Land. It was opened to the public as a park in 1914 and its name was changed in 1928 to the present one in memory of the great pioneer of the Chinese Democratic Revolution. The Working People's Cultural Palace used to be Taimiao (the Supreme Ancestral Temple), where tablets of the deceased dynastic rulers were kept.
The stream in front of Tian'anmen is called Waijinshuihe (Outer Golden River), with seven marble bridges spanning over it . Of these seven bridges, historical records say the middle one was for the exclusive use of the emperor and was accordingly called Yuluqiao (Imperial Bridge). The bridges flanking it on either side were meant for the members of the royal family and were therefore called Wanggongqiao (Royal's Bridges). Farther away on each side of the two were bridges for officials ranking above the third order and were named Pinjiqiao (ministerial Bridges). The remaining two bridges were for the use by the retinue below the third order and were called Gongshengqiao (common Bridges). They are the one in front of the Supreme Ancestral Temple to the east and the one in front of the Altar of land and Grain to the west.
The two stone lions by the Gate of Tian'anmen, one on each side were meant as sentries. They gaze toward the middle axis, guarding the emperor's walkway. In front of the gate stands a pair of marble columns called Huabiao. They are elaborately cut in bas-relief following the pattern of a legendary dragon. Behind the gate stands another pair of similar columns. The story of Huabiao may be traced to a couple of sources. One of the versions accredits its invention to one of the Chinese sage kings named Yao, who was said to have set up a wooden pillar in order to allow the ordinary people to expose evil-doers, hence it was originally called a slander pillar. Later it was reduced to a signpost, and now it serves as an ornament.
The beast sitting on the top of the column is called "hou", a legendary animal, which is said to have been a watcher of an emperor's behaviour. He was doing such duties as warning the emperor against staying too long outside the palace or indulging in pleasure and urging him to go to the people for their complaints or return in due time. Therefore, the two pairs of beasts were given the names "Wangjunhui" (Expecting the emperor's coming back) and "wangjunchu" (Expecting the emperor's going out) respectively.
In the old days, Tian'anmen, as a part of the Imperial City, was meant for important occasions. The two rows of chaofang (antechamber), on the sides behind the main gate, were reserved for civil and military members of the government waiting for imperial audience and in front of the gate, were offices of imperial administration.
On October 1, 1949, chairman Mao Zedong proclaimed on Tian'anmen Rostrum the founding of the People's Republic of China. Since then Tian'anmen has been the symbol of New Chine\a. Chairman Mao's portrait is hung above the central entrance, flanked by two slogans:" Long Live the Great Unity of the Peoples of the World". Today, the splendour of Tian'anmen attracts million of visitors from all over the world. The Rostrum on its top was opened in 1988 to the public for the first time in its history. It offers a panoramic view of the Square and the city proper.
Situated due south of Tian'anmen, the Square has an area of 44 hectares (109 acres) that can accommodate as many as one million people for public gatherings. It has witnessed may historical events in China's modern history and is a place for celebrations on such festive days as international Labour Day on May 1st and national Day on October 1st.
Around the Square are several famous buildings:
1 The Great Hall of the People
This is one of the largest congressional buildings in the world. Built in 1959, the hall consists of three parts: a 10, 000-seat auditorium in the center, a banquet hall in the north wing facing Chang'an Street, with a seating capacity of 5, 000, and offices for the Standing Committee of the National Peoples' Congress of China in the south. In addition, thirty-four reception chambers are named after various provinces, autonomous regions and municipalities directly under the Central Government, plus Hong Kong and Macao. Each is different from the other in decoration and furnishings to stress their local features.
2 The Museum of Chinese History and the Museum of the Chinese Revolution These two museums were also built in 1959. The museum of Chinese History houses a permanent exhibition in four parts, covering the entire process of Chinese history spanning from 1.7 million years ago to 1919:
1) The Primitive Society (1.7 million years ago to the 21st century BC);
2) The Slave Society (21st century BC to 476 BC.);
3) The Feudal Society (475 BC. To 1840 AD.);

It is 38 meters (124ft 8 in) high, the loftiest of its kind ever seen in the country. Not only is it an historic memorial for immortal heroes, but also it is an artistic work of excellent architectural value.

4 Chairman Mao's Mausoleum
Chairman Mao Zedong, the founder of the People's Republic of China, passed away on September 9, 1976. In commemoration of this great man, a mausoleum began to be constructed in November 1976, and was completes in August the following year. The Mausoleum was officially opened on September 9, 1977.
The mausoleum is surrounded by four groups of sculpture. East of the northern entrance is the sculpture depicting the period of the New Democratic Revolution (1919-1949), and west of it is the one signifying the great achievements of the Chinese people during the period of socialist revolution and construction since 1949. The sculptures in front of the southern gate are figures of workers, peasants soldiers, intellectuals, technicians and children.
Inside the Mausoleum are three main sections: A white marble statue of Chairman Mao is mounted on a platform in the front lobby. On the wall behind the statue is a 24-metre-long (79-foot-long) tapestry, a fine needlepoint work with beautiful landscapes of the country.
In the main hall there is a crystal coffin, in which Chairman Mao's body lies stately with the Communist Party's flag covering over him.
