The Beijing Ancient Observatory (simplified Chinese: 北京古观象台; traditional Chinese: 北京古觀象台; pinyin: Běijīng Gǔ Guānxiàngtái) is a pretelescopic observatory located in Beijing, China. The observatory was built in 1442 during the Ming dynasty, and expanded during the Qing.

As one of the oldest observatories in the world, the Beijing Ancient Observatory grounds cover an area of 10,000 square meters. The observatory itself is located on a 40 by 40 wide meter on a 15 meter tall brick tower, an extant portion of the old Ming dynasty era city wall that once encircled Beijing. Several of the bronze astronomical instruments are on the platform, and other armillary spheres, sundials, and other instruments are located nearby at ground level. It is operated as a museum in affiliation with the Beijing Planetarium.

History[edit]

The layout of the observatory

It was said that in 1227, the Jin dynasty transferred the ancient astronomical instruments from Kaifeng to the first observatory in Beijing. In 1279, the succeeding Mongols under Kublai Khan built a new observatory just north of the current observatory. After the Mongols, Zhu Yuanzhang, the founding Ming Emperor, transferred the instruments from Beijing to Nanjing. When the Yongle Emperor came to power, he had craftsmen make copies of the instruments in Nanjing and sent them to the Beijing observatory.

The current observatory was completed in 1442. It assisted the Ming and Qing astronomers in their observation reports for the Emperor. As he was considered the "Son of Heaven", the movements of the heavenly bodies were an important affair. Another function was to assist sea navigation, with Muslim scholars recruited for their expertise in the area.[citation needed] In the mid-17th century, after winning an astronomy contest, the Jesuit Ferdinand Verbiest was awarded complete charge of the astronomy observatory by the emperor. In 1673, he supervised the rebuilding of some of the instruments. He and other Jesuits helped to further develop the observations of the stars and the planets.

During the later stages of the Qing dynasty, members of the Eight-Nation Alliance stole some of the instruments. However, as World War I drew to a close, the instruments were returned to China by the French and German governments. An early seismograph of Zhang Heng's design used to be housed at the observatory. Some of the instruments from the Ming era are now at Purple Mountain Observatory in Nanjing.[1][2]
