In 2001-2002, the Institute of Archaeology, Chinese Academy of Social Sciences, excavated the ruined main gate Changhemen of the Northern Wei palace-city on the Han-Wei Luoyang city-site. The work revealed all remains of the gate foundations, the left and right towers in front of the gate, the square between the towers, and parts of the courtyards on the western and eastern sides of the gate. The unique structure and layout of the gate towers display strong chronological features and special function with dignity above defense, which exerted great influence upon later buildings of this sort. The gate was constructed in the Cao Wei period. Its discovery has great value to inquiry into the form and location of the Luoyanggong Palace built in the early Cao Wei period as well as the location of the Han period North Palace in ancient Luoyang City.展开更多

Through the excavation it can be affirmed that the building is a large-sized pavilion-style palace-gate with three passageways of the Northern Wei period and shares the same shape and structure with the Changhemen Gate,the first,main entrance of the palace-city. The two gates must have been designed in a package planning. The discovery has great importance to researching into the layout of Northern Wei Luoyang Capital and the evolution of the architecture of ancient Chinese capitals.展开更多

Having an irregular plan, the site measures 733m in circumference and occupies an area of about 50,000sq m, with a gate in the northeast. The cultural deposits in the city fall into two phases. The early phase is roughly conformable to the early remains in the seventh area of the Fenglin city-site and the Guntuling culture in the Anbanghe River valley and goes back to the Western and Eastern Han period. The late phase of remains is similar to the Fenglin culture and corresponds to the Wei-Jin period. The trail excavation sheds light on the construction period, building methods, works order and abandoning factors of the city. Another piece of information from the site is about the use of ploughs in lical people's farming in the Wei-Jin period.展开更多

This foundation is located to the north of ChangheGale and Building Foundation Ⅱ and the due south of Taiji Hall. It is the main body of a hall-typed architectureconsisting of the large-sized rammed-earth foundation, the rammed-earth partitions and column network composed oframmed-earth plinths and column pits. The side doors on the eastern and western sides, the rammed-earth foundationsof auxiliary buildings and the grounds on the southern and northern sides of the main body and the imperial path toits south comprised the architectural complex unit together. Most of the tiles unearthed in this excavation were thepolished tiles of the Northern Wei Dynasty, while some tiles made in the Han and Western Jin Dynasties were alsofound. Referred to the stratigraphic relations, this building foundation is inferred to be constructed and mainly used inthe Northern Wei Dynasty, and partly extended and used in the lat phase of the Northern Dynasties.展开更多
