Unjusa or Unju Temple is a Korean Buddhist temple located in Hwasun County, South Jeolla province, South Korea. It is 26 km (16 mi) southwest of Hwasun County or 40 km (24 mi) south of Gwangju. Compared with other temples in South Korea, this temple has an unusual collection of stone Buddha statues and stone pagodas, so Unjusa is often referred to as the mysterious temple. Among several assumptions regarding its origin, the most widely known one is that Monk Doseon founded the temple based on geomancy during the late period of Silla Dynasty (57 BC – 935 AD), but the origins remain unverified.
Unjusa is designated as Treasure #312 and is the site of the well known Treasure #796, Unjusa Gucheung Seaktap (Nine-story Stone Pagoda at Unjusa).Four excavations and two academic studies occurred at the temple, conducted by Jeonnam National University Museum from 1984 to 1991, but the exact time the temple was built, by whom, and construction methods remains a mystery.
