The Xuanrenmen Gate is the only city gate in the eastern wall of the east of Sui and Tang Luoyang city. During 1996- 1997, in the course of capital construction within the old city of Luoyang, it was excavated by the Tang Luoyang City Archaeological Team, IA, CASS. Limited by the work site, the excavation covered only the southern gateway and a part of the eastern one. The remains are in rather a good condition and can be divided into two phases. The early city-gate was used from the full Tang to the end of this dynasty, and had the southern, middle and northern gateways; the late city-gate was used from the Five Dynasties period the mid Northern Song dynasty, and had only one gateway, i.e. the middle gateway of the early city-gate. On the site, stone and wooden structural members of the Tang city-gate remain in a great number and variety. The revelation of the ruined Xuanrenmen Gate is of great importance to the inquiry into the layout of the east of the Sui and Tang eastern capital; and the discovery of plentiful structural members of the gate provides significant material for studying the architectural features of city gates in the Tang period.
