Prasat Pre Rup was built as the state temple by king Rajendravarman ( 944 - 968 AD). It was dedicated to the Hindu god Shiva. It is a temple mountain of combined brick, laterite and sandstone construction.The temple 's name litterally means in Khmer language as "change the body".

Located in Siem Reap Angkor Archaeological Park, just south of the East Baray or eastern reservoir (currenly dried), Pre Rup is aligned on a north-south axis with the East Mebon temple, which is located on what was an artificial island in the baray. Pre Rup's extensive laterite and brick give it a pleasing reddish tone that is heightened by early morning and late afternoon sunlight.

The temple has a square lay-out and two perimeter walls. The outer enclosure is a platform bounded by a laterite wall, 117 meters N-S by 127 meters E-W. A laterite causeway gives entry from the east; unfortunately, a modern road cuts across it. The four external gopuras are cross-shaped, having a central brick section (consisting of three rooms flanked by two independent passageways) and a sandstone vestibule on both sides. To either side inside the eastern gate is a group of three towers aligned north to south. One of the towers appears to have never been built or to have been dismantled later, however they are later additions, probably by Jayavarman V. Further ahead, through another gate, libraries lie to either side of the walkway on the second platform. Just before the entrance there is a stone "cistern", but scholars believe it was a basement for a Nandi bronze statue rather than being used for cremation ceremonies.

There is also a series of long distinct galleries running along each side, a distinctive feature of 10th century architecture that would be substituted by a continuous gallery from Ta Keo onward.

The final squared pyramid, measuring 50 m at its base, rises in three steep tiers a dozen metres in height to a 35 m square platform at the summit. The lowest tier is simmetrically surrounded by 12 small shrines. At the top, five towers are arranged in a quincunx, one at each corner of the square and one in the center. Deities carved as bas-reliefs stand guard at either side of the central tower 's eastern door; its other doors are false doors. The southwest tower once contained a statue of Lakshmi, the northwest tower a statue of Uma, the southeast tower a statue of Vishnu and the northeast tower a statue of Shiva. The last one has an inscription on door jambs that dates from Jayavarman VI and is the only proof of his reign at Angkor.
