“During the Ōnin War, construction was halted. Despite Yoshimasa’s intention to cover the structure with a distinctive silver-foil overlay, this work was delayed for so long that the plans were never realized before Yoshimasa’s death. The present appearance of the structure is understood to be the same as when Yoshimasa himself last saw it. This “unfinished” appearance illustrates one of the aspects of “wabi-sabi” quality.
“Like Kinkaku-ji, Ginkaku-ji was originally built to serve as a place of rest and solitude for the Shogun. During his reign as Shogun, Ashikaga Yoshimasa inspired a new outpouring of traditional culture, which came to be known as Higashiyama Bunka (the Culture of the Eastern Mountain). Having retired to the villa, it is said Yoshimasa sat in the pavilion, contemplating the calm and beauty of the gardens as the Ōnin War worsened and Kyoto was burned to the ground.”
