Sambisari is a 9th-century Hindu temple located at Sambisari hamlet, Purwomartani village, Kalasan, Sleman regency, Yogyakarta. The temple was buried about five metres underground. Parts of the original temple have been excavated. The temple is located about 8 km east of Yogyakarta near Adisucipto International Airport.
The temple emerged in July 1966 by a farmer when working on land that belongs to Karyowinangun. His hoe hit the carved stone which was a part of the buried temple ruins. The news of discovery reached the Archaeology office in Prambanan and the area was secured. The excavation and reconstruction works was completed in March 1987. The temple is thought to have been buried by an eruption of volcanic ash from the nearby Mount Merapi.
The discovery of Sambisari temple probably was the most exciting archaeological findings in Yogyakarta in recent years, leading to speculation about whether there are other ancient temples still underground in the vicinity, buried under Mount Merapi volcanic ash.
