Candi Plaosan, also known as Plaosan Complex, is one of the Buddhist temples located in Bugisan village, Prambanan district, Central Java, Indonesia. It is easily accessible from Yogyakarta by Surakarta road. Candi Plaosan covers an area of 2,000 square meters with an elevation of 148 meters above sea level.
Plaosan temple was built in the mid 9th century by Sri Kahulunnan or Pramodawardhani, the daughter of Samaratungga, descendent of Sailendra Dynasty, and who was married to Rakai Pikatan in the Hindu tradition. The Plaosan complex is an ensemble of two Buddhist temples, Plaosan Lor and Plaosan Kidul. The Ploasan temple complex is made up of 174 small buildings, 116 are stupas and 58 are shrines. Many of the buildings have inscriptions. Two of these inscriptions denote the temple as a gift of sanctuary by Rakai Pikatan. The dates of the inscriptions are between 825-850 AD. Although similar to the Prambanan 856 AD date, the complexes are not related. A new building technique distinguishes Prambanan from Plaosan temples.

Prambanan is the largest Hindu temple of ancient Java, and the construction of this royal temple was probably started by Rakai Pikatan as the Hindu Sanjayas answer to the Buddhist Sailendra’s Borobudur and Sewu temples nearby. The construction of Prambanan probably was meant to marked the return of Sanjaya dynasty to power after almost a century fell under Sailendra domination on Central Java.
A temple was first built at the site around 850 CE by either Rakai Pikatan or Balitung Maha Sambu the Sanjaya king of the Mataram Kingdom. According to Shivagrha inscription that wrote chandrasengkala ”Wwalung gunung sang wiku” (778 Saka/856 M), the temple was built to honor lord Shiva and the original name of the temple is Shiva-grha (the house of Shiva).[2] Indeed, some archaeologists propose that the idol of Shiva in the garbhagriha (central chamber) of the main temple is modelled after King Balitung, serving as a depiction of his deified self after death.[3].
The temple compound was expanded by successive Mataram kings such as Daksa and Tulodong with the addition hundreds of perwara temples around the chief temple. Prambanan served as the royal temple of the Hindu Kingdom of Mataram, with most of the state’s religious ceremonies and sacrifices being conducted there. At the height of the Mataram kingdom, scholars estimate that hundreds of Brahmins with their disciples lived within the outer wall of the temple compound. The urban center and the court of Mataram were located nearby, somewhere in the Prambanan valley.  (Source: http://en.wikipedia.org/wiki/Prambanan) Nov.7, 2009.

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 was accidentally discovered in July 1966 by a farmer when working on land that belongs to Karyowinangun. 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.
