Azuchi Castle
In 1976, the Japanese architectural historian Akira Naitō published what he believed to be a conclusive summary of the features of Azuchi Castle. He concluded that the "tenshu" was 46 meters in height, with a gilded octagonal belvedere on top. An atrium rose from the basement level to the fourth floor ceiling, supposedly influenced by the Jesuits, but with a stupa at the atrium floor center. However, the external design of Azuchi Castle is still debated. Another Japanese Architectural Historian, Miyakami Shigetaka, has accused Naitō of failing to corroborate his theory with enough documentation.
