Research for the Restoration of Suzakumon Gate

Research for the restoration of Suzakumon Gate started with excavations at the former site in 1964, and the production of a one-to-ten scale miniature model in 1965.

Research was then conducted into the materials and construction methods for 7 years from 1979, before “The research for the design and structure of Suzakumon Gate in Heijo Palace” was published and carried out for 3 years from 1986.

The reference materials in the directory indicated that the appearance of Suzakumon Gate was limited to the foundations and ground works to indicate the existence of stylobate platforms, columns positioned in proportion, and roof tiles found in the excavation. Utilizing these materials and referring existing ancient architecture and historical documents, the research and restoration continued.Occasionally assumptions were applied based on the knowledge accumulated for more than 100 years since the Meiji period through various cultural architecture restoration projects,
