Sangwonsa, Buddhist temple in Pyeongchang County, South Korea

Sangwonsa is a Buddhist temple complex on the slopes of Odaesan in Odaesan National Park, Pyeongchang County, Gangwon-do. It is a branch temple of Woljeongsa and belongs to the Jogye Order. The current buildings date from after a 1946 fire and were rebuilt in 1947 by head priest Lee Jong-wook. The grounds hold the 725 bronze bell, National Treasure No. 36, and a marble pagoda.

The temple complex was founded during the Silla period and served as a site for royal prayers during the Joseon dynasty to help ensure the nation's peace and stability. This sacred function highlights how the temple maintained political and spiritual importance across different historical eras.

Sangwonsa is a branch temple (malsa) of Woljeongsa under the Jogye Order. Its name comes from the two Silla princes Bocheon and Hyomyeong, who according to the Samguk Yusa each founded a hermitage where they saw a blue lotus bloom; the site was first called Jinyeowon and became Sangwonsa in the Goryeo period. King Sejo donated bowls, clothing and a set of the Tripitaka Koreana, and the temple kept tax exemption throughout the Joseon dynasty by his will.

Sangwonsa sits on the slopes of Odaesan inside Odaesan National Park, in Jinbu-myeon, Pyeongchang County; the 930 Seongnam-ro address in Sillim-myeon is wrong. The temple is reached on foot from the Woljeongsa area, and the mountain path climbs, so wear sturdy shoes and allow time for the ascent.

The temple's bronze bell, National Treasure No. 36, was cast in 725 and is 1.7 meters tall. Its inscription records that it was donated by a noblewoman named Hyudori, and its lotus-pattern striking point and flying apsaras carvings are considered among the finest of Silla bells.
