present a little informations and pictures about some of these temples
1. CANDI KALASAN (Kalasan Temple)
 Candi Kalasan, also known as Candi Kalibening
Candi Kalasan, also known as Candi Kalibening is Buddhist temple located 13 km east of Yogyakarta on the way to Prambanan temple,  on the south side of the main road 'Jalan Solo' between Yogyakarta and  Surakarta
. Initially constructed during the late 8th century. The design of Candi Kalasan underwent a considerable number of changes during the remainder of Central Java's Classic Age. One notable feature of the temple is its octagon-shaped roof, which featured carved images of the Tathagatas facing the four cardinal points, each of which was flanked by a pair of Bodhisattvas in bas-relief. It has been suggested that the Bodhisattva serial on the upper part of Kalasan represent the famous Eight Great Bodhisattvas of Mahayana Buddhism.

According to a Kalasan inscription dated 778 AD, written in Sanskrit using Pranagari Script, the temple was erected by the will of Guru Sang Raja Sailendravamçatilaka (the Jewel of Sailendra family) that succeed to persuade Maharaja Tejapurnapana Panangkaran (in other part of the inscription also called as Kariyana Panangkaran)  to construct a holy building for the goddess (boddhisattvadevi) Tara and also build a vihara (monastery) for buddhist monks from Sailendra family's realm. Panangkaran awarded the Kalaça village to sangha (buddhist monastic community). According to the date of this inscription, Kalasan temple is the oldest among temples built in the Prambanan Plain 
 
2. CANDI SEWU (Sewu Temple)
Candi Sewu is a complex of approximately 257 temples located in  Central  Java. The Javanese translation of Sewu is “one thousand  temples,”  although this was probably never the case. Part of the  Prambanan tourist  destination area, Sewu is located in Bugisan Village,  approximately 800  kilometers north of Prambanan and only 2 kilometers  to the north of the  Prambanan Temple.
 The Sewu historic area is nes tled in a valley between  the northern  Merapi volcano and southern Sewu mountain range at the  Yogikarta  border. Sewu is the second largest Buddhist temple in the  cental part  of Java and its proximity to the Hindu Prambanan Temple  seems to  indicate a harmonius co-existence of Hindu and Buddhist  followers throughout history in this area. A large number of other  archeological  sites surround the area.

A large number of other  archeological  sites surround the area.
The eighth century Sewu Temple compound is believed to have been a Royal   Buddhist Temple and important religious area at the end of the rule of   Rakai Pikitan, a Sanjaya Dynasty prince who married the Buddhist   princess, Pramodwahardani of the Sailendra Dynasty. Also an important   urban area and political domain during the mid-700′s AD, the temple   complex is currently being restored after suffering significant damage   from an earthquake in 2006. The main temple has been restored to prevent   its collapse and is off limits to tourists due to safety concerns
Historians and archeologists believe that the Sewu temple was  originally  named “Manjusrighra”, meaning “The House of Manjusri,”  translated from  an inscription dating from 792 AD. Manjusri is a  Boddhisatva or  “enlightened being” in Buddhist teachings who is the  incarnation of  wisdom. A Boddhistva is one who self-denies the pleasure  of nirvana or  divine enlightenment in order to assist others in the  achievement of an  enlightened state. Manjusri is represented in  illustrations with a book  in one hand and a sword in the other to  symbolize qualities of  intelligence and harmony by cutting the bonds of  ignorance. He is one of  the more important dieties being defined as a  spiritual friend, in  addition to both mother and father to other  Boddhisatvas.

 The buildings within the complex are arranged in a Mandala or  circular  pattern to assist in the enlightenment of those who meditate  within its  walls. Mahadeva is the largest central temple, which faces  east and is  surrounded by four rings of smaller temples. These smaller  temples are  temples of the Gods.

It is located about 130 meters north east from Kalasan temple. This temple was a two story building with wooden beams, floors,  stairs completed with windows and doors; all from organic materials  which now are decayed and gone. It is strongly suggested that the  original function of this building was a vihara 
 (Buddhist Monastery), a dwelling place for Monks. 
 The temple's name

  The three temples were located on a straight line, suggesting there was a symbolic meaning that binds these temples.
  "Between Mendut and Borobudur stands Pawon temple, a jewel of Javanese temple architecture. Most probably, this temple served to purify the mind prior to ascending Borobudur."
  The original name of this Buddhist shrine is uncertain. Pawon literally means "kitchen" in Javanese, which is derived from the root word awu or dust. The connection to the word "dust" also suggests that this temple was probably built as a tomb or mortuary temple for a king.[3]. Pawon from the word Per-awu-an (place that contains dust), a temple that houses the dust of cremated king. However who was the personage that entombed here is still unknown. Local people name this temple as "Bajranalan" based on the name of the village. Bajranalan is derived from the sanskrit word Vajra (thunder or also a Buddhist ceremonial tool) and Anala (fire, flame).

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 Sambis ari 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.
ari 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 the architecture style and ornaments of the building that resembles those on Prambanan, the findings of Hindu statues around the temple walls, and the lingga-yoni inside the main temple; historians concluded that Sambisari was a Shivaite  Hindu temple built around first or second decade of 9th century (circa  812-838). This conclusion was supported by the findings of gold plate in  vicinity engraved with letters that according to paleography was 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.
7. CANDI GEDONG SONGO (Gedong Songo Temle)
This  is a resort on the slope of mount Ungaran,  about 900 meters above sea  level. Gedong Songo (nine buildings), a  group of small 8th century  Hindu Javanese temples, can be reached  either by car or on horseback  from the town. Built at about the same  time as the temples of the Dieng  complex, Gedong Songo is one of the  most beautifully sited temple  complexes in Central Java and the views  alone are worth the trip.  Gedung Songo ('Nine Buildings') belong to the  earliest antiquities of  Java, they follow up the temples on the Dieng  Plateau directly, for  what about time. They were also built high in the  mountains in an area  full with volcanic activity; and they were also  from Hinduist origin.  But where the temples on Dieng Plateau are  somewhat squeezed into a  foggy valley, Gedung Songo are spread over the  higher parts of the  mountains, which guarantee a splendid view. On  clear days, the horizon  is one long row of volcanoes, from mount Lawu  in the east, towards  mount Sumbing, mount Sundoro and Dieng Plateau in  the west.
 
                   The  temples were built between 730 and 780, the first temple  excepted,  which could have been built some 30 years later. Gunung  Songo is not  the original name and also doesn't point at the number of  structures.  The number nine has a special meaning in the Javanese  culture, in which  there is a strong attachment to numbers. The temples  are located at  about the same distance from each other (100 meters, 200  meters) on a  naturally formed terrace of edge of a mountain. (source : indonesia-tourism.com) 
 
8. CANDI SUKUH (Sukuh Temple) Sukuh                temple

The temple stretches from the east to the west with the main                gate in the west. Sukuh Temple is decorated with wayang stone carvings                of Hindu origin, the only erotic temple in Java. The stepped pyramid                is like the ones in South America of the Maya culture. The temples                are distinctive compared with other ancient temples in Central Java                such as Borobudur and Prambanan, and its uniqueness lies in the                landscaping, statuettes, and relief. The temples occupy an 11,000m2                area and consist of three terraces, each connected with an ascending                alley. The most influential part is the last terrace, at the very                back of the compound. At this very sacred area, once erected a homogenous                phallic statue, which is now displayed at the National Museum, Jakarta.                Another interesting and controversial factor of this historical                site is the artistic relief on its floor, which depict male and                female organs symbolizing the birth of life. This kind of construction                is common in prehistoric time, especially in the megalithic era                of pundan berundak (terrace grave). The temple consist of three                terraces, the first terrace is the lowest level, followed by the                second and the third above it. The terrace are connected with stairs                to each other, each of it has an entrance gate. The temple has believed                to be constructed in the 15th century during the declining years                of Majapahit Empire. The relief found beside the first gate are                believed had mean (sengkalan) reads Gapura Buta Aban Wong and Gapura                Buta Anahut Bubut, meaning the year of 1359 saka or 1437 AD.
