Since the establishment of Luoyang, the eastern capital of Sui Dynasty, dingdingmen was successively designated as the main gate of waiguocheng by Tang, Houliang, houtang, Houzhou and Northern Song Dynasty, and was gradually abandoned until the end of Northern Song Dynasty. Dingdingmen, as the main gate of the south wall of Guocheng, lasted for 530 years. It is the oldest ancient capital gate in China.
