Candi Plaosan is located in Bugisan Village, Prambanan, Klaten, notably 1.5 meters eastward of Candi Sewu. This temple is an old complex constitutes of two area: Candi Plaosan Lor (north) complex and Candi Plaosan Kidul (south) complex. The carvind on Plaosan Temple is very refined and concise as that in Candi Borobudur, Candi Sewu and Candi Sari.

This temple is Buddhist temple and experts estimate this was built in Rakai Pikatan period of Hindu Mataram Kingdom, in the early 19th century. De Casparis cited this according to Cri Kahulunan inscription (842), that mentions that Candi Plaosan Lor was erected by Queen Cri Kahulunan and supported by her husband. Casparis stated that Sri Kahulunan is the title of Pranodhawardani, daughter of Samaratungga from Syailendra Dynasty. The daughter was Buddhist, married to Rakai Pikatan from Sanjaya Dynasty that was Hindu. There is other opinion around this. Candi Plaosan was built before Rakai Pikatan reigned, Sri Kahulunan was considered not as cited by Casparis, but she was the mother of Rakai Garung that reigned Mataram before Rakai Pikatan. Rakai Pikatan reign is deemed to be too short to built such big temple like Plaosan and he built perwara after main temple had been built.

Later on 2003, discovered inscription nearby Candi Perwara in Candi Plaosan Complex. This inscription was date back 9th century, made of piece of gold 18.5 x 2.2 cm, written in Sanskrit in Old Javanese letters. This inscription content is still unknown, but allegedly that this inscription strengthens that Candi Plaosan was built in Rakai Pikatan period.
