Naksansa () is a Buddhist temple in Yangyang, Gangwon Province, South Korea. It stands on the slopes of Obongsan Mountain (also called Naksan Mountain) and belongs to the Jogye Order. Established by Uisang in 671, it was designated as historic site in 2008.
Naksan is an abbreviation of Botarakgasan that refers to Mount Potalaka, the place where Avalokitesvara (Gwanseeum Bosal/Gwaneum) is believed to live. Naksansa is regarded as one of Gwandong Palgyeong (eight scenic sites of Gangwon) and one of 3 holy sites of Gwaneum.
Naksansa was founded in 671 by Uisang Daesa (Grand Master), a Buddhist monk during the reign of King Munmu, after he had returned from studying abroad in Tang. While meditating near the cave in which Gwaneum was believed to have lived, he was told by the deity to build the temple there. On the other hand, Wonhyo did not realize that the woman he met on his way to Naksansa was Gwaneum and could not enter the cave where Gwaneum was staying when he arrived at the temple.
Most of the temple was destroyed by a forest fire in early Goryeo except temples dedicated to Gwaneum and Jeongchwi Bosal. However, the entire temple was burnt down during Mongol invasions of Korea.
In the Joseon dynasty, the temple was repeatedly reconstructed and expanded by royal orders in 1467, 1469, 1631 and 1643.
The temple was completely burnt down in the Korean War. In 1953, Corps Commander Lee Hyeong-geun restored wontongbojeon (ìÂÂõ보ì Â, worship hall housing a statue of Gwaneum) and beomjonggak and Ven. Woncheol restored the rest in 1976.
Most of Naksansa was destroyed by a fire that started in the surrounding forest on April 5, 2005. The Naksansa bronze bell, a bell King Yejong made for his father in 1469, was also lost in the fire. Although it was designated as treasure in 1968, it lost its designation in July 2005. Later, a replicate of the bell was installed in the temple.
Cultural Heritage Administration built wontongbojeon and Hongyemun in 2007 and Binillu in 2009. As of 2015, the temple is restored. The restoration was based on Naksansado, a 1778 painting by Kim Hongdo.
