Yingtian Gate
The Yingtian Gate, Ying Tian Men (simplified Chinese: 应天门; traditional Chinese: 應天門) was the southern gate of the imperial palace in Luoyang during the Sui and Tang dynasties, and it may have been the largest city gate in ancient China. Ancient Japan constructed capital gates with the same names Ōtenmon (応天門) in the cities of Heian-kyō (present-day Kyoto) and Heijō-kyō (present-day Nara).
