The Daigoku-den Hall of Heian Jingu Shrine is modeled after the main hall and the Da-uchiura of Heian-kyo, the center of Kyoto in the Heian period, and Daigoku-den in particular was reproduced as the central facility. Daigoku-den Hall was once the place where the emperor conducted important ceremonies and state affairs at the Heian-kyo court, and symbolized the dignity and prestige of the court. Although the present Daigoku-den was designed as a scaled-down version of the Heian-kyo Imperial Palace's Dainairi, its grandeur and opulence perfectly express the characteristics of the court architecture of the time. The contrast between the red pillars, green roof tiles, and white plaster walls is extremely beautiful and evokes the aesthetic sense of the Heian period. The roof is finished in the hiwadabuki (cypress bark) style typical of Japanese architecture, creating a harmonious design throughout the building. Inside the Daigoku-den Hall, there is a “Takamikura,” a reproduction of the Emperor's throne. This was the seat of the emperor used in court ceremonies during the Heian period, and its presence adds to the historical significance of Daigoku-den. The Daigoku-den at Heian Shrine is not merely an imitation of a building from the past, but was constructed as a symbol of the re-evaluation of Japanese history and culture during the Meiji era. Through this building, visitors can experience the atmosphere of the Heian period and the historical significance of Kyoto. Furthermore, Daigoku-den still plays an important role in connecting the traditional and the modern, as it is the place where many festivals and events are held today.
