The site of the Northern Song Dynasty's capital city,Dongjing,is a typical example of an ancient-modern overlapping city,with the central axis and the layout of the core urban streets still in use today.The imperial palace of Northern Song Dongjing,also known as the Imperial City,is roughly located in the present-day Longting Park area of Kaifeng,Henan Province.Guided by the theory of reconstructing ancient-modem overlapping cities,this paper examines the continuity of the streets and alleys near the imperial palace of Northern Song Dongjing.The relative positions of the streets,government offices,and key points south of the imperial palace suggest that the palace was located in the northwest corner of the inner city,with the city's central axis lying in the eastern half of the palace.This asymmetrical layout was likely constrained by the already established street patterns of the old Bianzhou city from the Tang and Five Dynasties periods.Based on this research,the paper also argues that the location and distribution of the imperial palace significantly influenced the architectural layout of the palace,the neighborhood system of the inner city of Northern Song Dongjing,the Jin Dynasty's Nanjing Imperial City,and the Ming Dynasty's Zhou Prince's Mansion.
