Abstract:In the Imperial Tombs of the Ming and Qing Dynasties, the Three glazed-tile architectures , Lingqinmen, behind the Xiangdian (Xiangdian is a type of sacrificial hall in the tomb that worships spiritual positions and deceased spirits) are often ignored compared with the main buildings such as the Xiangdian and the Underground Palace. The research of the Tomb-gate Architectures including its location, function, and evolution is with great significance to comprehensively study the imperial tombs. This research attempts to trace the origin of the architectural prototypes, and explores the development and evolution of Lingqinmen, providing reference and supplementation for the study of tomb architectures, especially Imperial Tombs. These were done by literature researches and field works on the same functions and locations as Lingqinmen in the imperial tombs of all dynasties after the establishment of aboveground buildings in tombs.
