Ruins of Taiji Hall of ancient Luoyang city, Henan province

The ruins of Taiji Hall in Luoyang city in Central China's Henan province are part of China's oldest palace.

The hall was the central part of the imperial palace of the Northern Wei Dynasty (386-557).

Archaeologists have cleared 3,000 square meters of the ruins and worked out the scale, range and structure of the palace building. They estimated that the original palace might have covered an area of 100,000 square meters.

Taiji Hall was composed of a central main hall and two side halls each in the east and west.

The palace building has been replicated ever since in building imperial palaces through the Sui, Tang, Song, Yuan, Ming and Qing dynasties, even spreading to East Asia and beyond. It played a significant role in the history of ancient capital.

Ruins of Taiji Hall of ancient Luoyang city in Henan province was listed among China's top 10 archaeological discoveries in 2015.
