Bomunsa Temple is located on Seongmodo Island in the Gangwondo Island district. The temple is on Sangbongsan Mountain, one of three mountains that make up the Samsan-myeon area. Like many temples in Korea, the foundation date is unknown but it is believed to have been founded in 635 during the reign of Silla Queen Seondeok. The temple faces out to the ocean, with the sound of waves reaching all the way to the main building.

The main courtyard is fragrant with the scent of an aromatic tree, designated Incheon Natural Monument No. 17. Beyond the tree is a gathering of Buddhist scuptures and a large grotto.
