Sambisari is a 9th-century Hindu temple located at Sambisari hamlet, Purwomartani village, Kalasan, Sleman regency, Yogyakarta, Indonesia. 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.
Based on architectural and ornamental similarities to another Hindu temple in Indonesia, Prambanan, the presence of Hindu statues around the temple walls, and the lingga-yoni inside the main temple, historians have concluded that Sambisari was a Shivaite Hindu temple built around the first or second decade of the 9th century (circa 812-838). This conclusion was supported by the findings of a gold plate in the vicinity engraved with letters that according to paleography were used in early 9th century ancient Java.
According to Wanua Tengah inscription III dated 908 that contains the name of kings that ruled Mataram Kingdom, the temple was probably built during the reign of Rakai Garung (ruled 828-846). However, historians also consider that the construction of a temple was not always issued by a king. Lesser nobles might have also ordered and funded the construction.
Visitors must descend the flight of stairs on the western side to reach the central part of the temple, the base of which is 6.5 meters lower than the current ground level.
The outer parts are 8 meter wide terraces. Recent excavations revealed the outer layer of walls surrounding the temple, which cover a wider area. Only the north-eastern part of this outer wall was excavated, the rest still is buried underground.
The Sambisari complex was surrounded by a rectangular wall made from white stone measured 50 meters x 48 meters. In this main yard, there are eight small lingga, four located at the cardinal points and four others in the corners.
The Sambisari temple complex consisted of a main temple and a row of three smaller pervara (guardian) temples in front of it. The center pervara temple measures 4.9 x 4.80 meters, while northern and southern pervara temple measures 4.80 x 4.80 meters each. Each of these lesser temples has no stone body and roof, and only consists of base part and balustrades.
The main temple is facing west and took form of a square with size 13.65 meters x 13.65 meters. The temple has no real base (foot) part, so the sub-basement part also serves as the base part. The siar is adorned with makara supported by dwarf (gana). There is no Kala carving on top of the main gate. By ascending the stairs, the visitors can reach the rectangular 2.5 meters wide gallery, which has balustrades surrounding the main temple.
On this gallery there are 12 umpak (stone base), 8 bases took round shape and 4 others are square ones. This stone bases probably used to support wooden pillars, suggesting that the main temple used to be covered by a roof structure made from organic materials that now are already decayed and gone.
The body of the main temple measures 5 x 5 meters and 2.5 meters high. Around the temple walls are niches containing statues of Hindu gods, topped by Kala’s head. In the northern niche, there is a Durga statue, in the eastern niche, a Ganesha statue, and in the southern niche, an Agastya statue. The portal to the main room is on the western side. The entrance is flanked by niches that once contained guardian statues of Mahakala and Nandisvara. Inside the temple reside a yoni, measured 1.34 x 1.34 meters and 1.18 meters high. On the north side of the yoni, there is a water spout supported by a Nāga serpent. Atop the yoni is a lingga measuring 0.29 by 0.29 metres (11 in × 11 in) at the base and 0.85 metres (2 ft 9 in) high.
