Hōryū-ji (法隆寺, Temple of the Flourishing Dharma) is a Buddhist temple that was once one of the powerful Seven Great Temples, in Ikaruga, Nara Prefecture, Japan. Its full name is Hōryū Gakumonji (法隆学問寺), or Learning Temple of the Flourishing Law, the complex serving as both a seminary and monastery.
The temple was founded by Prince Shōtoku in 607, but according to the Nihon Shoki, in 670 all buildings were burned down by lightning. However, reconstructed at least 1,300 years ago, the Kondō (main hall) is widely recognized as the world's oldest wooden building.
A fire that broke out during the dismantling and repair of Kondo on January 26, 1949 destroyed a mural of the Asuka period, a national treasure, and shocked the Japanese. Based on this accident, the day when the fire broke out is now fire prevention day for cultural properties.
