Ginkakuji is a Zen temple that was established in 1482 by Ashikaga Yoshimasa, a Shogun. It was originally his private retreat (which he hid in while Kyoto was ravaged by war) but he decreed that it would become a temple at the time of his death. It is called the Silver Pavillion because it was originally going to be covered in silver to match the Golden Pavillion on the other side of Kyoto, but those plans were put on hold and never resumed.
