The Hall of Supreme Harmony is the largest hall within the Forbidden City in Beijing, China. It is located at its central axis, behind the Gate of Supreme Harmony. Built above three levels of marble stone base, and surrounded by bronze incense burners, the Hall of Supreme Harmony is one of the largest wooden structures within China. It was the location where the emperors of the Ming and Qing dynasties hosted their enthronement and wedding ceremonies. The name of the Hall was changed several times throughout the past few centuries, from its initial Fengtian Dian, later to Huangji Dian in 1562 and to the current one by the Shunzhi Emperor of the Qing dynasty in 1645.
Together with the Hall of Central Harmony and Hall of Preserving Harmony, the three halls constitute the heart of the Outer Court of the Forbidden City.
The Hall of Supreme Harmony rises some 30 metres above the level of the surrounding square. It is the ceremonial center of imperial power, and the largest surviving wooden structure in China. It is eleven bays wide - with the main room being nine bays wide - and five bays deep, the numbers nine and five being symbolically connected to the majesty of the Emperor.
