The interior

As the symbol of imperial power, the interior of the hall is very luxurious. The floor is paved with golden bricks that are not really made of gold but really precious. In Chinese culture, the emperor is the incarnation of dragon. So the hall is dominated by dragon designs on the throne, columns, windows and ceilings. The golden throne sits on a platform in the north of the hall, with an elegant wall screen behind and three gilded columns on each side. In front of the throne, there are mythical beasts, cranes, and incense burners, which have their own symbolic meaning. The extraordinary ceiling above the throne changes in shape and has a dragon with a pearl in his mouth. The pearl is said to be able to distinguish whether the emperor is the legitimate inheritor or not. It would fall off the ceiling if an illegitimate successor ascended the throne.

Architecture

The Hall of the Taihe Dian, the main hall of the Forbidden City, is 27 m high, 64 m wide and 37 m deep. It has a roof with double eaves and is decorated with carved dragons and phoenixes, most of which are golden. The building is raised on a three-tiered terrace, 8 m high, enclosed by marble barrier, while those around the same courtyard were kept lower so as to set off the magnificence of the hall.

The red walls, pillars and yellow glazed roof-tiles, and the dougong and beams decorated with dark-green designs of dragons, phoenixes and geometric figures, are clearly visible against the grey background of Beijing. Begun in 1406, the fourth year of the reign of Yongle (Ming dynasty), the City was completed fourteen years later; partial reconstruction took place during the period of the Qing dynasty. Twenty-four emperors lived in and ruled China from the Forbidden City over nearly 500 years.
