Yumedono ("Hall of Dreams"), a building in the Hōryū-ji Buddhist temple complex in Ikaruga, Nara Prefecture, Japan. The hall, which was built in 739, acquired its common name in the Heian period, in keeping with a legend that says a Buddha arrived as Prince Shōtoku, who had originally commissioned the temple, and meditated in a hall that existed there.Photo: Frank J.
