From the Shooting Hall of the Forbidden Court to the Main Hall of the Outer Court——Exploration of the Hanyuan Hall Site in the Daming Palace of Tang Dynasty
Hanyuan hall is the main hall of the outer court in the Daming Palace,holding a prestigious position.It has been excavated twice by the Institute of Archaeology of the Chinese Academy of Social Sciences,once in 1959-1960 and again in 1995-1996.The academic community has different understandings about the site of Hanyuan hall.The main differences revolve around whether there existed different stages of the Hanyuan hall site,and whether the Hanyuan Hall of the Tang Dynasty was reconstructed on the foundation of the Guande Hall of the Sui Dynasty.Through an analysis of significant architectural remnants,such as the Yongding pillar holes around the foundation,the remaining column base stones on the platform and the rammed earth walls,it is discovered that the Yongding columns were erected to support a secondary floor,resulting in changes to the foundation of the main hall.Additionally,the construction of three rammed earth walls and comer column was carried out to modify the double-eave roof structure,leading to alterations in the column network.These findings confirm the existence of different construction periods at the Hanyuan Hall site,with the early site being the Guande Hall built in the third year of the first emperor,Emperor Wendi of the Sui Dynasty(583 AD).
